Adding STNeuroNet to the niftynet pipeline

In the provided Software/STNeuroNet folder, a number of python codes for our network is provided. These files need to be placed in the correct locations under the niftynet package. Assuming that the niftynet package directory is (for example, C:/Program Files/Anaconda3/env/stneuronet/Lib/site-packages/niftynet for Windows when the environment stneuronet was created), each file should be placed in the locations listed below:

File	Destination Folder
application_driver.py	<niftynetroot>/engine
application_factory.py	<niftynetroot>/engine
windows_aggregator_grid.py	<niftynetroot>/engine
pad.py	<niftynetroot>/layer
grid_warper.py	<niftynetroot>/layer
stneuronet.py	<niftynetroot>/network
segmentation_application.py	<niftynetroot>/application
