[MITgcm-support] set initial flow field

[Martin Losch]

Hi Xumingquan

the parameter names are uVelInitFile and vVelInitfile, w will be computed from div(u) = 0. Be aware that specifying initial velocities with inconsistent hydrography can lead to strong initial shocks and may require very short time steps (initially).
Here are some verification experiments that use these flags
