[gradsusr] PYGRADS problem with PDEF

[Davide Sacchetti]

Dears,
We noticed some errors using pygrads with ctl files including pdef
directives. Our grid is rotated, we used either pdef bilin or pdef 
rotllr, but errors on grid.meta in ganum._exp2d() are the same
(exception raised on line 234 of ganum.py)

It might be that there are some problems in parsing the first 20 values
from ipc_save, or are we doing anything wrong?

Using debug at line 224:
        (Pdb) grid.meta
        array([  1.84689701e+25,   1.57883589e-19,   7.77242201e+31,
                 7.14408185e+31,   4.10594102e+04,   1.93472401e-19,
                 7.21432390e+22,   1.15785712e+27,   7.22507008e+28,
                 2.44565409e+20,   1.12586784e+24,   2.72450326e+20,
                -2.86196307e-23,   9.03173995e-39,   0.00000000e+00,
                 5.83155401e-39,   6.17844824e-39,   6.16194655e-39,
                 5.83155401e-39,  -1.19687500e+01], dtype=float32)
        

configuration
grads:   v2.0.1.oga.1
python:  2.7.3
pygrads: 1.1.b5
