ancestors within the YY subset (not just the closest one(s)).  Suggested
by Paul K.

get fetch all to ignore LRG_gene this makes it slower but if you are getting all the them then this will be insignificant time difference

if more than one projection then check against the slcie you are projecting too to make sure it is the corect one. This is for multiple assemblys where a feature can go to nmore then one slice

mv load_alt_slice_gff.pl to load_alt_splice_gff.pl

Added sanity check to _objs_from_sth to allow fetching DnaAlignFeatures without a slice, so that we can retrieve userdata features for the entire genome

Added calls to allow web code to fetch an individual marker, so we can show low map weight markers on Location/View

Folded some older comments for readability.

fixed the various methods routines. this was not working at all but no one ever used it so was never noticed. Needed now for uniprot swissport having a different percentage cutoff
