killed lots of tests
transcript.to_tbl with proper mock gene
gene.remove_contig_id thing
Got one of the gene to tbl tests to pass
More to_tbl tests passing
All to_tbl tests pass
all fix_phase tests pass
Gene.make_positive tests pass
totally broken code but tests are passing
mrna.make_positive test
took out dependency on add_child side effect
Moved fix_feature_lengths to GFFFeature and added tests
match_cds_and_exon_end works + tested
create_starts_and_stops works + tested
All tests passing, transvestigator appears to work, need to look at it more in depth before merge with master
