Implementation of disease mutation class

[gsheynkman]

Need a class that represents disease mutations (genetic variants, mendelian disease mutations, complex disease variants, cancer autosomal and somatic variants) that are mapped to Position and Residue objects.

Placeholder for module -> isomodules/isomut.py

Code that could be used as a start -> isomodules_in_progress/mutation*.py

[gsheynkman]

Download and curate genetic variants from population databases (gnomad, exac), cancer databases (tcga, cosmic), complex disease (gwas), and mendelian disease (hgmd, clinvar)

Map to the transcripts and proteins

Lollipop plot for visualization - can see relationship between position of disease mutations and isoform and protein features.
