Multi-dimensional data

[shuds13]

Should there be any convention for multi-dimensional data.

If our data structure is a list of dictionaries, each dictionary entry could be multi-dimensional.

If libEnsemble is to have a wrapper to convert numpy structured arrays to list of dictionaries, what do we convert a 2d x value to. It could be a numpy array or should it be some native python type like a list/tuple.

Optimas seems to avoid by making each dimension a separate entry.
