#67 new bug
No weights will be given to module maps in homogeneous resolutions

Description
only mres and nres do care about "isHomog" attribute for homogeneous ideals.
nither syz nor sres nor lres set module weights!!!
something is wrong with the size of resolution (length is 1 too many than there actually are...) or conversion of resolution to list... For instance, nres seems to be somewhat defect. (length = 8!)
see attached example

notice empty "weights: ( ): " and right side is not a datum, assignment ignored

I have tried all this only with the conversion of resolution to list, and i must say that size behaves better this way, but sometimes(e.g. from sres) one may get another trailing zero entry (size: 4 instead of 3), which is imho not a big issue...
Unfortunately: the big issue remains: no modulo-weights :(

same with one explicite conversion of resolution to list
