calcGseaStatBatchCpp

Calculates GSEA statistic valus for all gene sets in 'selectedStats' list.

Takes O(n + mKlogK) time, where n is the number of genes, m is the number of gene sets, and k is the mean gene set size.

calcGseaStatBatchCpp(stats, selectedGenes, geneRanks)

`stats`	Numeric vector of gene-level statistics sorted in decreasing order
`selectedGenes`	List of integer vector with integer gene IDs (from 1 to n)
`geneRanks`	Integer vector of gene ranks

Numeric vector of GSEA statistics of the same length as 'selectedGenes' list
