mle.getPermutations: Generate the "adaptive walk" node permutations, starting from...
In lashmore/MolEndoMatch: Molecular Endophenotype Patient Matchmaking

This function calculates the node permutation starting from a given perturbed variable in a subset of variables in the background knowledge graph.

1	mle.getPermutations(sig.nodes, patient, ig.pt)

`sig.nodes`	- The names (as a character vector) of the variables that were significantly perturbed in the given patient.
`patient`	- The row number (integer) in data.pvals associated with the patient being processed.
`ig.pt`	- An igraph object of the background knowledge graph.
