Description

Add support for regular expression pattern matching to Trafodion's SQL dialect. The support will follow the design of the existing LIKE predicate, reusing (and/or refactoring) its code as needed. For run-time semantics, we will use the RE2 regular expression package (http://code.google.com/p/re2/).
