KeyError on deleting pygr.Data resource

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Save a resource to pygr.Data with no SCHEMA
2. Delete the resource (i.e. via pygr.Data.deleteResource )

What is the expected output? What do you see instead?
Expected output is nothing.  We see a KeyError instead:

What version of the product are you using? On what operating system?
Using MacOS v10.4 or v10.5

Please provide any additional information below.
The pygr.Data resource does in fact get deleted but a call is made to
delSchema() with a pygr.Data resource id of 'SCHEMA.name.of.resource'.  If
no schema was ever saved, this resource will never exist and thus retrieval
via "d=db.getschema(id) # GET THE EXISTING SCHEMA" will always produce the
KeyError.

See attached script and modified ecoli 'genome' file to reproduce.

added try: except KeyError clause to handle this.  We should add a test to the 
test
suite.
