all_featurelocs
*
* The records in the 'all_featurelocs' array are all properly arranged for easy iteration.
*
* However, access to the original alignment records is possible through the
* $feature->featureloc object. In the following ways:
*
* Alignment context #1:
* --------------------
* If the feature for this node is the parent in the alignment relationships,
* then those alignments are available in this variable:
*
* $feature->featureloc->srcfeature_id;
*
*
* Alignment context #2:
* ---------------------
* If the feature for this node is the child in the alignment relationsips,
* then those alignments are available in this variable:
*
* $feature->featureloc->feature_id;
*
*
* Alignment context #3:
* --------------------
* If the feature is aligned to another through an intermediary feature (e.g.
* a feature of type 'match', 'EST_match', 'primer_match', etc) then those
* alignments are stored in this variable:
* feature->matched_featurelocs
*
* Below is an example of a feature that may be aligned to another through
* an intermediary:
*
* Feature 1: Contig --------------- (left feature)
* Feature 2: EST_match -------
* Feature 3: EST --------- (right feature)
*
* The feature for this node is always "Feature 1". The purpose of this type
* alignment is to indicate cases where there is the potential for overhang
* in the alignments, or, the ends of the features are not part of the alignment
* prehaps due to poor quality of the ends. Blast results and ESTs mapped to
* contigs in Unigenes would fall under this category.
