Recode of the function set_cores() (returns True after setting the field (no double check), add support for single tuple)

If the NIST object contains multiples minutiae fields, the checkMinutiae() function will return a list of all minutiae after the checks

lstTo012 : check if the passed list is an AnnotationList or not. Raise error if the input data is not a list or an AnnotationList

Add the NIST.fingerprint.functions.changeFormatImage() to cast an input image to some output formats

Delete the RAWToPIL and PILToRAW function from the function.py, and use the same function from the MDmisc.imageprocessing library

Recode the 'NIST.traditional.NIST.load_auto()' function to copy all fields, and not to copy all data contained in the NIST object.

Add the function NIST.traditional.NIST.is_binary(), checking if a particular field is stored as binary data or not
