BVGetSizes
Returns the local and global sizes, and the number of columns. 
Synopsis
#include "slepcbv.h" 
PetscErrorCode BVGetSizes(BV bv,PetscInt *n,PetscInt *N,PetscInt *m)
Not Collective
Input Parameter
Output Parameters
|  | n | - the local size | 
|  | N | - the global size | 
|  | m | - the number of columns | 
Note
Normal usage requires that bv has already been given its sizes, otherwise
the call fails. However, this function can also be used to determine if
a BV object has been initialized completely (sizes and type). For this,
call with n=NULL and N=NULL, then a return value of m=0 indicates that
the BV object is not ready for use yet.
