runMutalyzer() function and added a new example script.

- Added sliceChromosome(), which returns an UD number given a chromosome
  accession number, a start and end and an orientation.
- Modified the runMutalyzer() function to also return a description on the
  chromosome.
Serializers.py:
- Added chromDescription to the MutalyzerOutput class (see webservice.py).

webservices.html, textmining.py, textmining_sample.txt:
- Added a small textmining example.
