Fast-forward
Replaced all instances of "new String()" with "Bytes.toString()" to
ensure we use the HBase default string charset encoding of UTF-8
as opposed to the Java default of UTF-16.

Added utility methods for creating indexes, indexed queries,
and executing indexed queries in Util and HIndexedTable.

Added support for LESS_OR_EQUAL and GREATER_OR_EQUAL for the
hybrid implementation. Added examples to client test code.

Disabled BenchmarkTest class due to missing jar support.

Other minor formatting in HTableIndexCoprocessor.
