     * Create an index table by morphing the CreateIndexStatement into a CreateTableStatement and calling
     * MetaDataClient.createTable. In doing so, we perform the following translations:
     * 1) Change the type of any columns being indexed to types that support null if the column is nullable.
     *    For example, a BIGINT type would be coerced to a DECIMAL type, since a DECIMAL type supports null
     *    when it's in the row key while a BIGINT does not.
     * 2) Append any row key column from the data table that is not in the indexed column list. Our indexes
     *    rely on having a 1:1 correspondence between the index and data rows.
     * 3) Change the name of the columns to include the column family. For example, if you have a column
     *    named "B" in a column family named "A", the indexed column name will be "A:B". This makes it easy
     *    to translate the column references in a query to the correct column references in an index table
     *    regardless of whether the column reference is prefixed with the column family name or not. It also
     *    has the side benefit of allowing the same named column in different column families to both be
     *    listed as an index column.
