Add protein_to_transcript in separate ncbi module

Jeroen F.J. Laros authored 9 years ago and Vermaat committed 9 years ago

Existing `transcript_to_protein` is factored out into a separate
`mutalyzer.ncbi` module.

Add Ter as a valid AA in the HGVS grammar

Previously, the `PSubst` rule did not register `MutationType`, so it
was a bit awkward how to check for a `p.` substitution. We can now:

    >>> grammar.parse('NP_00011.1:p.Asp23Tyr').RawVar.MutationType
    'subst'

Refactor unit tests using py.test

Especially lxml takes very long to install. By specifying the `-O0`
compiler flag this is reduced by more than half.

The actual unit tests are slightly slower with the non-optimized
C modules, but we have a netto win.
