I'm unfamiliar with this part, should we put xreader in another file?
decorator function take reader as input, and an enhanced feature function is returned. xreader is more likely a 1 reader n writer pool.

xmap_readers is like map_readers in decorator.py. They are truly decorators.
1. rename 'useXmap' to 'use_xmap' 2. add comments about exchanging train data and test data
