where /path/to/source is where all the images are stored
and /path/to/target is where images will be sorted
and optional argument for format for target directory structure

The source tag is optional. If not provided, it will take the
current directory.

The options are as follows:

-h --help              Prints this
-v --version           Prints version
-s --source            Directory to process. If not set will process
                       current directory
-t --target            Expression to remove from file name
-f --format            Optional format for target directory structure.
                       Default structure created under target directory
                       is yyyy/mmmm/yyyy_mm_dd
                       e.g. 2013/January/2013_01_13
                       The format is supplied as "yyyy/yyyy_mm_dd".
                       This will create a directory structure of the format
                       "2013/2013_01_13" under your target directory.
                       Where 2013 is a sub-directory under the target
                       directory and 2013_01_13 is a sub-directory under
                       2013
