MR_deleteInContext: now checks that the managed object is loaded in the specified context before deleting it.
Use existingObjectWithID: directly rather than checking the MOC reference.
Typo fix.
Converted spacing to tabs.
Added test for MR_deleteInContext: across multiple contexts.
Add support for converting numbers in imported data into NSString attributes on entities. Thanks to @xslim for this patch — closes #622.
Allow proper deletion of entities in other contexts, as per #419.
