Mixture number chosen to be 3 or 4 with each state initially having the
same number of mixtures. Plotted the TM segment length distributions,
which give us an indication of the grammar constraints. 

To Do:

(1) Grammar --> visualized and .mod file created. Still need to compute
	initial mean and covariance params.
(2) Segment Overlap --> see POV in Castrense paper.
(3) beta-sheet contact scores --> obtained from precision matrix values.
	These will give us an indication of local interaction strength.
	Generally people look at non-local interaction strength for
	beta-strands.
(4) Inputs --> different representations of the protein sequences.
