Module medpicpy.config

"""
This module allows setting of some global values that 
medpicpy references internally. 

cache_location refers to where the image data is stored 
when `use_memory_mapping` is set in a function call.

suppress_errors means that exceptions will not be thrown if 
an invalid path is read as an image. This may be desired for some 
large projects where there are non-image files hidden in the 
dataset. 

rescale means that the images are automatically scaled 
between 0 and 1 as they are loaded. Useful for machine learning 
projects.
