Add or subtract two maps of the sky.

Usage:

[-help]: Display usage information.
[-sky1 filename1]: Name of file containing first sky.
[-sky2 filename2]: Name of file containing second sky.
[-out filename_out]: Name of output sky file.
[-file_type file_type_str]: String specifying file types.
[-ext ext (optional)]: File extension for map files.
[-sub subtract]: Logical to specify whether to subtract maps (default false). If maps are to be subtracted then result = sky1 - sky2.
