In lianos/multiGSEA: A unified interface to a plethora of gene set enrichment analysis methods

This is a utility function that is called by [.GeneSetDb and is not exported because it is not meant for external use.

1 2	## S3 method for class 'GeneSetDb' subset(x, keep)

`x`	a `GeneSetDb()`
`keep`	logical vector as long as `nrow(geneSets(x, active.only=FALSE)`

DEBUG: If keep is all FALSE, this will explode. What does an empty GeneSetDb look like, anyway? Something ...

We want to support a better, more fluent subsetting of GeneSetDb objects. See Issue #12 (https://github.com/lianos/multiGSEA/issues/12)

a GeneSetDb that has only the results for the specified genesets.
