Arbitrary number of stages during training

[dleebrown]

Should be an easy feature to implement - just put the second through n stages inside a loop, where the program first checks to see if "DO_TRAIN(n)" exists in the parameter file and if so fetches LEARN_RATE(n), etc, and runs training, otherwise returns.

I don't really think this is worth implementing. It would add more parameters and would bloat the parameter file, when 1 or 2 stages of training works fine.
