Rebasing the current net with main

Closes #19

In order to accomodate data coming from multiple sources, we need to replace the hardcoded inputs with variables whose values are extracted from the dataset during the code run.

Files updated:

1. loaddata.py
2. Model.py
3. train.py

Files Removed:

1. 'NN_pred.py'

Files Added:

1. main.py

In train.py, the .nc data files are read and the variables are extracted and normalised. This part should be taken out of train.py and be kept in a separate preprocessing.py file, to keep train.py common for different data sources. train.py can be converted into a module instead. We can also have a test notebook in the repo.

This should be resolved by PR #34

This is too out-of-sync and not tested properly.
