Features can share a set of tables, and they do so by default.

This can be configured by setting a boolean on the SFT when creating the schema in the AccumuloDataStore.
It is undefined since we have a link to an existing FeatureSource which has had its backing tables deleted.

For this WIP, I commented these out in order to things up.

Should we 
A) let the exceptions bubble up? or
b) catch them and return 0 results?
