Added presentations, fixed a bug in the numberConversion() webservice function

and added a couple of functions to the webservice.

doc:
- Added all presentations given on Mutalyzer.

doc/TechnicalReference/bnf.tex:
- Updated the documentation of the BNF.

Mutalyzer.py:
- Added a check for a valid start position in the __rv() function. If it is not
  set, the parser has accepted the variant description, but did not do anything
  more (unimplemented variant types for example). An ``unknown error'' is
  returned for now.
- Added the following to the output object in the __ppp() function, needed by
  the runMutalyzer() function of the webservice:
  - Original genomic reference sequence.
  - Mutated genomic reference sequence.
  - Original RNA sequence.
  - Mutated RNA sequence.
  - Original CDS sequence.
  - Mutated CDS sequence.
  - Original Protein sequence.
  - Mutated Protein sequence.
  - Alternative Protein sequence.

webservice.py:
- Added a function getTranscriptsByGeneName() that returns a list of
  transcripts, given a gene name.
- Fixed the getTranscriptsRange() function (see Mapper.py).
- Added the sequences described above in the Mutalyzer.py section to the output
  of the runMutalyzer() function.
- Added the summary of the output messages to the return object of the
  runMutalyzer() function.
- Added a getGeneAndTranscipt() function, that given a genomic reference
  sequence and a transcript accession number (NM_...) returns the gene name and
  transcript variant. 

Serializers.py:
- Modified the MutalyzerOutput class to contain the values described in the
  Mutalyzer.py and webservice.py section.

Scheduler.py:
- Modified a call to chrom2c(), (see Mapper.py).

Mapper.py:
- Added an extra check on the start location (also see Mutalyzer.py, first
  point).
- Modified the chrom2c() function to use an additional argument to control the
  return type. It can now either return a list or a dictionary.

Db.py:
- Added a function get_TranscriptsByGeneName(), for the
  getTranscriptsByGeneName() function of the webservice.

VarInfo.py:
- Added (commented out) debug code.

index.py:
- Modified a call to chrom2c(), (see Mapper.py).

sp.py:
- Added examples for (some of) the new functions of the webservice.
