[MITgcm-support] MNC_MAX_ID too small for 24 tiles

[Matthew Robert Mazloff]

Hello,

MNC_MAX_ID = 1000, is hard coded into the model.  However, when I break the
model into 24 tiles, this value is too small.  Is there any reason why I
shouldn't change this value to 1500 so I can run the model with 24 tiles?  Why
is there a max number of allowed indices? 

Thanks,
Matt
