Added function to theano DBN to make the DBN symmetric, i.e.
make the last n_layers/2 weight matrices of an even layered RBM
equal to the transpose of the first n_layers/2 weight matrices
Merge branches 'master' and 'add_DBN_symmetric_function'
Changed finetuning cost to binary cross entropy, and removed symbolic
parameters relating to the logistic output layer, since those parameters
are not relevant to gradient computation (and theano will cry if they
are included in the dbn's parameter list)

Changed layer architecture and function of DBN to mimic document summarization
paper
-Changed structure of hidden units in layers to [1000, 250, 10, 250, 1000, n_ins]
-Added functionality of making weight matrices symmetric on every finetuning

Added script to parse 'cleaned' data from australian dataset

'Cleaned' data from australian dataset batches involves:
Deleting all data up until first quotation mark preceding the title of the
first document in the feature list
Deleting last 2 characters (curly brace and a square brace)

Modified DBN to load parsed data from australian dataset
