Is there a way to print the matrix name so that -mat_view_info prints it out.

Instead of

Matrix Object:
  type=mpiaij, rows=200, cols=200
  total: nonzeros=40000, allocated nonzeros=40000
  total number of mallocs used during MatSetVal

it should print

Matrix Object: <MATRIX_NAME>
  type=mpiaij, rows=200, cols=200
  total: nonzeros=40000, allocated nonzeros=40000
  total number of mallocs used during MatSetVal

It'll be nice to have the matrix name printed out cause sometimes it gets confusing when there are a lot of matrices you are working with. 
Either the user can set a name and it could be printed out in mat_view_info or even better if in some way the variable name can be used directly.

What do you think?

Shri
