Collective on Grid

	bd	- The marker for the boundary to apply conditions along
	field	- The field to which the conditions apply
	diag	- The scalar to be placed on the diagonal
	f	- The function which defines the boundary condition
	ctx	- The user-supplied context

	A	- The system matrix
	b	- The Rhs vector
