Class NumericRangeQueryNodeProcessor
This processor is used to convert TermRangeQueryNodes to NumericRangeQueryNodes. It looks for NUMERIC_CONFIG set in the FieldConfig of every TermRangeQueryNode found. If NUMERIC_CONFIG is found, it considers that TermRangeQueryNode to be a numeric range query and convert it to NumericRangeQueryNode.
