void ELFDTD22::execute	(	const Grid &	grid,
		const CartPosition &	sig_loc,
		Function *	signal,
		const double &	time_span
	)

See notes on 2012-05-14 for the expression of the update equations.

From the grid and the cartposition to calculate the location of the hard source.

Pre-allocate the memory space for the field quantities

Current field - refers to the current (n for p and n+1/2 for u, )

Precedent field - refers to the one occuring immediately before the current (n-1 for p and n-1/2 for u )
