New script bin/convertGmapCoords.py to convert gmap results from rescur to pseudochromosome coordinates.

new rule gmapIndexTarget to prepare the whole genome index of the target genome. This index is needed to rescue genes without any mapping result in targeted mapping and gmap on target

now use all isoforms of genes when anchoring genes with gmap only (failed genes with targeted mapping approache)

BUG: remove -w from the fgrep command in the split per chrom rule. This cause a bug resulting into empty output

bug in  mapHomologousRegions shell command: need to use {wildcards.chrom} instead of {chrom} in the shell to properly expand the chrom variable
