TINKERPOP-2438 Introduce GremlinScriptChecker
Even though TINKERPOP-2438 is already done this is a bit of a follow on to that change. The GremlinScriptChecker performs the same exact task as the GremlinAstChecker but it does so with regex parsing which should be faster than processing a full AST. I've left the GremlinASTChecker where it is because I wonder if there isn't yet some usage for more rigorous sort of checks we might come up with in the future or perhaps have checks that only work well with AST processing. It can be rem [...]
