ascii files

Hi David,

I created a class to handle simple ascii files with root. You can use it if you want.
http://www.fynu.ucl.ac.be/users/v.roberfroid/work/stuffs/matrixRoot_html/matrixRoot.html This documentation must be updated. The code works with all version of root > 3.02.
I put in attachment the code source.

Regards,
Vincent
