Initialized arrays arrays that held values from the previous time step. Now initialized to zero. One array was not zero initially and caused N to grow.

fixed an error in one of the extensions go4 -->g04
deleting backup editor files
Added a few more extensions
input files for Wye simulations and 2006 Delaware
