New module call_scilab

[Sylvestre Ledru]

Hello,

Just to let you know that I am working on the creation of a new module
called "call_scilab". The goal of this module is to highlight the
possibility to call Scilab engine from other languages (like Python...
Hello Vincent ;) ) and to write more examples with each data types, more
documentation, etc.

Basically, it is just moving files into this module. It should not be a
problem.
