Detailed Description

Border data in CSR format.

This is the border data in CSR format.  Review of CSR:
Ap: is the array of sizes (in number of nonzero entries)
    in the Sparse Row.  Example: 
    [0 5 14 27 84 85 100] (5 in first row (row 0) in Ai[0:4]) 
                          (9 in row[1], Ai[5:13]), etc        

Ai: is the array containing the column numbers of the nz 
    entries in the sparse row.  Example: 
    [0 3 4 7 8 1 5 ......] (row 0): X00XX00XX000.....
                           (row 1): 0X000X000000.....

Ax: would store the actual values of the sparse matrix 

Each row corresponds to a border *node* - so the actual send and
receive arrays are puffed up to contain a number of matrix values
required for nremote_dof * nlocal_dof.
