Morpho

Need a new data package componenet from Morpho. This component represents a
resource (in the EML sense), and most importantly, a "dataset resource"). Thus,
it has mechanisms for storing all of the state info regarding a dataset, can
access the client-framework to read/write parts of the dataset locally and to
the metacat, and has a easy-to-understand mechanism for viewing a dataset in a
window (which it should register with the framework). This should be
implemented as a Morpho plugin, so it needs to implement all of the plugin
interface methods. Chad is taking the lead on this, with assistance from Dan.
