- Made a member function of RawVar() called description() that gives the HGVS

  description of the stored raw variant.
- Made a function that returns an allele description given a list of raw
  variants.
- Removed the hgvs member variable from RawVar().
- Removed the HGVS description generation from DNA_description().
- Started refacoring the DNA_description() function.

TODO: rolling for insertions and duplications is not working properly.
