High memory usage during "triples"

[davidcmarkham]

When running the algorithm as R_frontend.R, the process will slow severely and use a considerable amount of memory often resulting in a crash.

This occurs when the following line is executing:

triples <- exhaustive_search(data, labels, 3, sort(as.numeric(pairs[1,c(3,4)])), genes)

The code needs examining to check for any memory that is being allocated and not freed

If the "triples" is run on a system with sufficient memory (recommend 64GB or more), this will complete after a few hours. There will be ways that this could be made more efficient that should be investigated.
It's worth noting that the memory required will vary depending on the input data and which conditions are selected as stresses.
