Re: ascii files

Hi Vincent,

You misunderstand my comment .
I see you using the matrix class to store 2-dimensional tables (compare it
to pouring an Antwerp's Bolleke in a Heiniken glass) . That makes not a lot of sense , matrices have group properties etc . This falls in the same category as the TGraph constructor with a TVector
argument .

What ROOT needs is a class to store N-dimensional arrays .

Since Rene claims that the functionality, your class offers, is already available,
a tutorial seems to be appropriate to point people in the right direction .
