mle.getEncodingLength: Minimum encoding length (MLE)
In lashmore/MolEndoMatch: Molecular Endophenotype Patient Matchmaking

This function calculates the mininmum encoding length associated with a subset of variables against a background knowledge graph.

1	mle.getEncodingLength(ig, path, pvals, ptID)

`ig`	- An igraph object of the background knowledge graph.
`path`	- The filepath to a directory you will store patient-specific RData files in.
`pvals`	- The matrix that gives the perturbation strength significance for all variables (columns) for each patient (rows)
`ptID`	- The row name in data.pvals corresponding to the patient you specifically want encoding information for.
