model files repetitive

[jsadler2]

The code in the model files is still quite repetitive. For example:
https://github.com/UVAdMIST/Norfolk_Groundwater_Model/blob/e330dcac26a123aa3b991948af7502c8a60fbcb8/Model/Rivanna_HPC/keras_mmps043_fullBS_fcst_lstm_rivanna.py

compared to

https://github.com/UVAdMIST/Norfolk_Groundwater_Model/blob/e330dcac26a123aa3b991948af7502c8a60fbcb8/Model/Rivanna_HPC/keras_mmps043_stormBS_fcst_lstm_rivanna.py

The only thing that is different (from what I can tell) is the training data. So I think you can have a lot of this code in a different file and call it without repeating.
