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.
Fixed assert statement for abstract entities

Test Changes
Casting my line
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.
It’s more desirable to ignore clang warnings for the individual lines where the dubious code occurs, rather than for a whole class.
Merge pull request #544 from BitSuites/develop

Update assertion of abstract entity types to use `isKindOfEntity:` rather than a pointer comparison
