DESCRIPTION:
------------
If a parameter is missing, the user is notified by a DEEP_NOTIF_WARNING with DEEP_MSG_CONFIG_NOT_FOUND.
The missing parameter is added with the default value specified by DEEP_CONFIG and user is notified of the
addition of the parameter by a DEEP_NOTIF_WARNING with DEE_MSG_CONFIG_ADDED.
If a parameter is found successfully, it is converted to the data type specified by 'dtype' in DEEP_CONFIG.
If a parameter cannot be converted to the required data type, it is replaced with the default from DEEP_CONFIG.
PARAMETERS:
-----------
NB: Both parameters are only for use when check_config calls itself.
:param dictionary: dictionary to compare self.config with.
:param sub_space: list of strings defining the path to the current sub-space.
