gt made the following changes to MakeGridFromScratch and MakeGridFrom... in order to have initial regolith thickness and other variables read from input file and assigned at the start of a run: - tempnode constructor is called with input file as argument, which will read   in default initial values for variables like regolith thickness - in order to have tempnode's variables assigned to newly created nodes, I   replaced the AddNodeAt() call with AddNode( tempnode ) so that as nodes are   added they will have the correct initial values.
