Implementation of #153. (I guess there weren't any tests for that option, hmm.)
Clean trailing whitespace
get_indexed_slices: key_start -> start_key (for API consistency)
get_indexed_slices: Continue to support key_start for backward compat
Can you add a test for the new API?
Fix Cassandra::Mock to also accept start_key just like the real thing
Beef up tests for get_indexed_slices, test :start_key/:key_start
Add test for create_index_clause
Add tests for create_index_expression
Disable Mock tests for create_index_clause/expression
Had to rewrite the tests for get_indexed_slices a bit, but there you go. I also took the opportunity to add tests for create_index_clause and create_index_expression.
Ensure that create_idx_expr is tested like create_index_expression
Updated 0.8 schema for new test introduced in #155
