Run a HOMER known transcription motif analysis for all DMRs,
hypermethylated DMRs, and hypomethylated DMRs. The function requires HOMER's
findMotifsGenome.pl script to be in the path (i.e. module load homer)
and for the genome of interest (see perl /path-to-homer/configureHomer.pl -list)
to be installed through perl /path-to-homer/configureHomer.pl -install human.
