The PIAModeller which contains all the nice functions should consume a file (or PIACompiler) instead of PIA compilation file

[ypriverol]

Currently, the only way to apply some statistics on top of a standard file format is with PIACompiler and this needs to be written in an PIA file to be consume by modeller rather than a data structure. This needs to be changed for the user in order to do PIAModeller on top of a standard file format.

An implementation which passes the compilation directly to the modeller, instead of writing it to a file, should fix this and is a very good thing to have.
