FindOverlap: Given a list of two pathway results, find the overlap between...

The result of the spatial pathway identification is a two-column matrix, where each row represents the numeric identifiers of the causal direction of the pathway, so 1 4 3 2 would indicate there is a pathway from component 1 to 4, and from 3 to 2. If we use multiple methods to find these, it is useful to find the overlap - pathways reported from both methods. This method does that, effectively taking the intersection of the two matrices and returning the results in a similar matrix.

1	FindOverlap(results, remove = c("same", "different"))

`results`	A list containg two 'pathway' matrices
`remove`	Which results to keep: if `"same"` then 1 1 would be reported but 1 2 discarded, but if `"different"` then 1 2 would be reported but 1 1 discarded (useful for finding pathways that don't go from same component to same component)
