Create single-gene FGS
Each network node X becomes an FGS itself, so that e.g. each ID 'X' generates a list entry named 'X', the content of which is c('X'), i.e. this same gene/protein. The total length of the FGS list then equals the number of nodes in the network. This is a way to create single-gene "quasi-pathways" for a more specific network enrichment analysis.
