Added output-mode to append the log file, not overwite it. Removed parameter verbose for Matrix Reader.

Commented out checking for head and tail of warpList, as they don't contain values, they're just marks to the end of the list.

Preliminary templating of WarpInfo and WarpList. Preliminary fix of mistake where WarpList would loop infinitely. Added checkpoints. Committing for backup purposes.

Added verbose option for MatrixReader to be true by default. Added provisional log-file folder creation. Commiting for backup purposes.

Added verbose options for MatrixReader. Changed order of meta data columns. Commented out adding error messages and added related FIXME.

addWarp( const int, const int, const int, const int * ) takes int, but
in balanceLoad is given IndexType!! recast or rewrite warp list/info
using IndexType?

Removed commented out getType test call, as the test is not implemented in such a way to test all formats.
