[Qgis-developer] Processing algs documentation and createAlgorithmHelp

[Arnaud Morvan]

Hello

I've see that processing algs documentation have been refactorized, for 
now there is one .rst file for each group instead of one file for each 
algorithm in the past.
This should have been made to reduce the number of files.

On another side, there is some functions in processing.tools.help that 
create the help files for algorithms, the old way, one file for each 
algorithm, with title level shifted compared to new help files.

Accordingly, updating an algorithm documentation is now much more 
complicated.

Furthermore, there is, in QGIS-Documentation master branch an algorithm 
description which should have been merge with old format (one file in a 
group folder).
