Great news! It will be very useful for custom implementations. Thanks a lot for your help!

> Some custom index implementations require the base table's metadata to validate their
creation options. For example, the options of these implementations can contain information
about which base table's columns are going to be indexed and how, so the implementation needs
to know the existence and the type of the columns to be indexed to properly validate.
> The attached patch proposes to add base table's {{CFMetaData}} to Index' optional static
method to validate the custom index options:
> {{public static Map<String, String> validateOptions(CFMetaData cfm, Map<String,
String> options);}}
