Adding CropImage.py
Adding CropImage.py

A python script used to crop larger images (e.g. SDSS frames) into user-specified images. This script is a neat wrapper around the astropy Cutout2D( ) function.

Current issues:
 - Not sure if cropping on images where x-axis = Dec and y-axis = RA has the correct WCS information after cropping.
