[in]	nnodes	(int) - the number of nodes on the element
[in]	local_node_ids	(int*) - array of length nnodes containing node numbers local to process
[in]	elem_nvars	(int) - number of solution variables active on the element
[in]	elem_vars	(int*) - array of length elem_nvars that has the integer code for each variable
[in]	node_physics_mat	(SMAT_PHYSICS*) - an array of SMAT_PHYSICS structs that contains variable info for each node
[in]	nodal_physics_mat_id	(int*) - array of integers that gives the nodal physics mat id

global_to_local_dbl_ivars()

void global_to_local_dbl_ivars	(	double *	local_vals,
		int *	nodeIDs,
		int	nnodes,
		int *	map_array,
