c13421b10a Matrix: Added (i, j) addressing to allow support for addressing blocks of the matrix 
This change brings OpenFOAM into line with the standard matrix
addressing in other C++ libraries for better interoperability.

767ffc3c7b Matrix: Replace the row-start pointer array with computed offsets 
The row-start pointer array provided performance benefits on old
computers but now that computation is often cache-miss limited the
benefit of avoiding a integer multiply is more than offset by the
addition memory access into a separately allocated array.

With the new addressing scheme LUsolve is 15% faster.
