Identify and annotate partial gene features

[rsajulga-nmdp]

Identified by @mmaiers-nmdp:

Source	GFE
HML	HLA-DPB1w0-0-123-73-1896-2-809-29-0-0-0
GFE Database	HLA-DPB1w2-1-50-73-1896-2-809- 3-12-1-11

exon2-intron2-exon3-intron3 gene features are shared between the HML sequence and reference sequence (using GFE DB).

The flanking gene features (Intron 1 and exon 4) are partial.

Need to identify these partial gene features and assign a p to indicate partial features.
