* New functions global_v_norm2(), global_p_norm2(), global_div_norm2()
compute the L2 norm of velocity, pressure, and divergence.
* The L2 norm of the vector f is defined as:
\sum_{all elements} ( \int_{element} (f*f dA) ) / A
where A is the volume of the domain.
* The convergence criterion is controlled by parameter "accuracy" under
"[CitcomS.solver.vsolver]". The iteration stops if
(norm(div(rho*V))/norm(V) < accuracy) or
( (norm(dV)/norm(V) < accuracy) and (norm(dP)/norm(P) < accuracy) for
the last two iterations )
* The default value of "accuracy" becomes 1e-4.
* The input parameters "tole_compressibility" and "relative_err_accuracy"
under "[CitcomS.solver.vsolver]" are gone.
* The mass matrix E->MASS becomes double precision (was single precision).
