        dataset_name is the path to a JSON file (https://docs.python.org/2/library/json.html)
        containing a description for a dataset.

        Any extra parameter values supplied here will be passed down to the
        feature_coordinators requested in features_to_vary.

        The JSON file should contain the following entries:

            :'name': Name of the dataset (string, default=basename(dataset_name))
            :'length': Number of images in the dataset (integer, default=number of files in directory of dataset_name minus 1)
            :'description': Description of the dataset (string, default="")
            :'source': Citation of paper for which the dataset was created (string, default=name)
            :'filename_template': Path to the images with placeholders ({placeholder_name})
            for inherent features and the image number, e.g. "filename_template": "images/image{i}.png"
            (default={current_image}.jpg)
            :'inherent_features': Dictionary specifying how to access inherent features; value is used in eval().

            Currently, the label of the pattern generator
            ('pattern_label') as well as the image number
            ('current_image') are given as parameters to each callable
            supplied in inherent_features, where current_image varies
            from 0 to length-1 and pattern_label is one of the items
            of pattern_labels. (python code, default={'i': lambda params: '%02d' % (params['current_image']+1)}

            Example 1: Imagine having images without any inherent
            features named as follows: "images/image01.png",
            "images/image02.png" and so on. Then, filename_template:
            "images/image{i}.png" and "inherent_features":
            "{'i': lambda params: '%02d' % (params['current_image']+1)}"
            This replaces {i} in the template with the current image number + 1

            Example 2: Imagine having image pairs from a stereo webcam named as follows: "images/image01_left.png",
            "images/image01_right.png" and so on. If pattern_labels=['Left','Right'], then
            filename_template: "images/image{i}_{dy}" and
            "inherent_features": "{'i': lambda params: '%02d' % (params['current_image']+1),
                                   'dy':lambda params: 'left' if params['pattern_label']=='Left' else 'right'}"

            Here, additionally {dy} gets replaced by either 'left' if the pattern_label is 'Left' or 'right' otherwise

    def __init__(self,dataset_name,**params):
        """
        dataset_name is the path to a folder containing a
        MANIFEST_json (https://docs.python.org/2/library/json.html),
        which contains a description for a dataset.  If no
        MANIFEST_json is present, all image files in the specified
        folder are used.

        Any extra parameter values supplied here will be passed down
        to the feature_coordinators requested in features_to_vary.

        The JSON file can contain any of the following entries, if an
        entry is not present, the default is used:

            :'dataset_name': Name of the dataset (string,
            default=filepath)
            :'length': Number of images in the dataset (integer,
            default=number of files in directory matching
            filename_template)
            :'description': Description of the dataset (string,
            default="")
            :'source': Citation of paper for which the dataset was
            created (string, default=name)
            :'filename_template': Path to the images with placeholders
            ({placeholder_name}) for inherent features and the image
            number, e.g. "filename_template": "images/image{i}.png".
            The placeholders are replaced according to
            placeholder_mapping.  Alternatively, glob patterns such as
            * or ? can be used, e.g. "filename_template":
            "images/*.png" (default=path_to_dataset_name/*.*)
            :'placeholder_mapping': Dictionary specifying the
            replacement of placeholders in filename_template; value is
            used in eval() (default={}).
            :'inherent_features': Features for which the corresponding
            feature_coordinators should not be applied
            (default=['sf','or','cr'])

            Currently, the label of the pattern generator
            ('pattern_label') as well as the image number
            ('current_image') are given as parameters to each callable
            supplied in placeholder_mapping, where current_image
            varies from 0 to length-1 and pattern_label is one of the
            items of pattern_labels.
            (python code, default={'i': lambda params: '%02d' %
            (params['current_image']+1)}

            Example 1: Imagine having images without any inherent
            features named as follows: "images/image01.png",
            "images/image02.png" and so on. Then, filename_template:
            "images/image{i}.png" and "placeholder_mapping":
            "{'i': lambda params: '%02d' % (params['current_image']+1)}"
            This replaces {i} in the template with the current image
            number + 1

            Example 2: Imagine having image pairs from a stereo webcam
            named as follows: "images/image01_left.png",

            "images/image01_right.png" and so on. If
            pattern_labels=['Left','Right'], then filename_template:
            "images/image{i}_{dy}" and "placeholder_mapping":
            "{'i': lambda params: '%02d' % (params['current_image']+1),
            'dy':lambda params: 'left' if
            params['pattern_label']=='Left' else 'right'}"

            Here, additionally {dy} gets replaced by either 'left' if
            the pattern_label is 'Left' or 'right' otherwise

        If the directory does not contain a MANIFEST_json file, the
        defaults are as follows:
            :'filename_template': filepath/*.*, whereas filepath is
            the path given in dataset_name
            :'patterns_per_label': Number of image files in filepath,
            whereas filepath is the path given in dataset_name

        which contains a description for a dataset.  If no
        MANIFEST_json is present, all image files in the specified
        folder are used.

        Any extra parameter values supplied here will be passed down
        to the feature_coordinators requested in features_to_vary.

        The JSON file can contain any of the following entries, if an
        entry is not present, the default is used:

            :'dataset_name': Name of the dataset (string,
            default=filepath)
            :'length': Number of images in the dataset (integer,
            default=number of files in directory matching
            filename_template)
            :'description': Description of the dataset (string,
            default="")
            :'source': Citation of paper for which the dataset was
            created (string, default=name)
            :'filename_template': Path to the images with placeholders
            ({placeholder_name}) for inherent features and the image
            number, e.g. "filename_template": "images/image{i}.png".
            The placeholders are replaced according to
            placeholder_mapping.  Alternatively, glob patterns such as
            * or ? can be used, e.g. "filename_template":
            "images/*.png" (default=path_to_dataset_name/*.*)
            :'placeholder_mapping': Dictionary specifying the
            replacement of placeholders in filename_template; value is
            used in eval() (default={}).
            :'inherent_features': Features for which the corresponding
            feature_coordinators should not be applied
            (default=['sf','or','cr'])

            Currently, the label of the pattern generator
            ('pattern_label') as well as the image number
            ('current_image') are given as parameters to each callable
            supplied in placeholder_mapping, where current_image
            varies from 0 to length-1 and pattern_label is one of the
            items of pattern_labels.

            (params['current_image']+1)}

            Example 1: Imagine having images without any inherent
            features named as follows: "images/image01.png",
            "images/image02.png" and so on. Then, filename_template:
            "images/image{i}.png" and "placeholder_mapping":
            "{'i': lambda params: '%02d' % (params['current_image']+1)}"
            This replaces {i} in the template with the current image
            number + 1

            Example 2: Imagine having image pairs from a stereo webcam
            named as follows: "images/image01_left.png",

            "images/image01_right.png" and so on. If
            pattern_labels=['Left','Right'], then filename_template:
            "images/image{i}_{dy}" and "placeholder_mapping":
            "{'i': lambda params: '%02d' % (params['current_image']+1),
            'dy':lambda params: 'left' if
            params['pattern_label']=='Left' else 'right'}"

            Here, additionally {dy} gets replaced by either 'left' if
            the pattern_label is 'Left' or 'right' otherwise

        If the directory does not contain a MANIFEST_json file, the
        defaults are as follows:
