- renamed *.py scripts to *.py.in.
- edited all these scripts and replaced hardcoded paths by cmake variables
- edited CMakeLists.txt to add installation instructions for these scripts.

**About issue #14 (changes in master.py.in and createAsciidocDB.py.in)

For a given run, we have several informations: date and time, database, system, user, python/paraview versions, number or found/processed files, number of complete/incomplete/failed reconstructions, total time and a link to the run's results html page

For a given pipeline step:
-> (i.e a table cell), 'success' variable is used to color background (which means a red cell indicates a failed step.)
-> the complete command is included in plain text
-> execution times are rounded to the thousandth

**About issue #13 (changes in master.py.in and creation of createAsciidocSummary.py.in)

A new, global table is produced (asciidoc+html), summarizing runs.
- Runs are identified by their date and time of execution.
For each run:
- We present system informations, statistics and a link to the run's results page.

** About issue #15 (slight changes in master.py.in and creation of Examples/MeshFromMRI/generic/rorpo.cfg)
- Whole databases can be processed (e.g. /data/vivabrain) via master.py --inputpath.
- The generic directory is now used as a default directory for .cfg files. For now, only rorpo.cfg is present.
- Therefore, the whole database can only be run up to the RORPO step.
