Typo in Identity Xref function, variable should be $xref_end, not $xref_start

If $load_transcripts is true, do not do lazy loading in any case (including when the number of genes is 1).

Fixed example to create and edit an AltAlleleGroup.

Check that translations exist before comparing the sequences

If a translation object does not exist, we do not try to access its sequence

Check that an analysis exists before calling logic_name on it, needed for testing where a full object might not exist. And just good sanity.

New Transcript added to the test file transcript.txt. So updated the tests that checks for the transcript count.

Updated fetch_all_by_Transcript method to optionally filter by feature_type (dna_align or protein_align features)

Add seq_region_start and seq_region_end to Slice, as a Slice is always relative (or is) a toplevel coordinate system, a simple alias to start/end() are possible.

New attrib table for dna_align_features
