Nexus is bumpin!!!

Revised Matrix to be row[col] instead of col[row], and to have one
matrix of values instead of a matrix of onOff/value sub-matrices, for
transmitting/readability purposes. Moved getHandlers into nxManager,
now nx.getHandlers. Scaled Position transmit data to 0-1 instead of
0-self.width and 0-self.height.
