as ID has to be unique, exons have no ID field, only Name

updated test module

- for ID field, concatenate object type before the stable id
- if gene biotype is protein_coding, the so term is replaced by gene

updated to release 76

[ENSCORESW-543]. Version is left undef to match the healthchecks expected behaviour (null instead of empty).
The getter method returns the empty string in case version is undef (matching the method signature of the
documentation).
The equals method use the getter method instead of accessing the attribute directly.

Removed functionality to get INSDC xrefs from FlyBase; these are better determined with the xref pipeline, which attaches them to translations rather than genes.

[ENSCORESW-820] Retiring obsolete canonical transcript script. Use select_canonical_transcripts.pl instead.

circular slices. In this case, do not use seq_region_start|end to compute min_start|end as the
feature might be crossing the origin of replication and the comparisons to determine min_start
and max_end might then be nonsense.

still need to remove manually any mappings which would have been added before for that patch

circular slices. In this case, do not use seq_region_start|end to compute min_start|end as the

use production database to fetch biotype groups

[ENSCORESW-840]. seq region boundaries are fetched from the db (for slices stored in the db) in case
of circular chromosomes. This is because it is impossible to recompute the seq_region_start|end for
a feature in a circular slice since the transformation operated in method _objs_from_sth in the
corresponding adaptor is not invertible.
For some of the features (e.g. those in the Bio::EnsEMBL::FeaturePair hierarchy), we can't query
the db and the methods seq_region_start|end return undef even if the feature is on a slice.

all modules take the same arguments and have the same behaviour
the only differences should be related to the columns specific to a given feature

add splicingEvent tests for basic methods

* hotfix/comparadocumentation:
  [ENSCORESW-841] - Doxygen output. Make PerlFilter ignore additional packages in a module, to prevent confusion in Compara codebase.

We want people to give us bugfixes or cool features which help
everyone. So we're making the rules to contributing easier.

added extra_data/external_data column to insert for storing DnaAlignFeatures

use code directly in get_attrib method

A fix for the fix. Originally we started with passing through Slice
for the aligned feature but this is wrong. We need to assert the
hit feature Slice which we do not have. This change reverts the
_check_start_end_strand() method back to its original functionality.
