Log:
This is kind of a hack, but it fixes pickling of 2D data objects -- useful for
pushing and pulling objects across the network in IPython.  Most of the 2D data
objects assume that self.field is a string, but here the field variable was
bound to the local namespace "field", which was uninitialized in the local
namespace.  So, it was usually set to something like PreShock_Density, when it
should be set to the variable fields.  But to match up, we ensure it's a list
and take the first element.
