Next steps for Mikey

Adding the electronic SLD to the multiclass classifier.  MC is nearly done.  Have to turn into ascii files and add capability to tf code.

BDT code.  Look into multi-class BDT.

Add the following functions to dnn_tools.py:
1. fcn that reads in data files and returns pandas dfs
2. fcn that sets up the dfs after being read in
3. fcn that generates all of the labels once the data frames are read in (this is all vague rn)
