Minor updates to ExprTk 

Updated unknown symbol resolver interface to handle all types (scalar, string and vector)
Added compile-time check for vector indexing when using constant values
Added return statement enable/disable via parser settings
Added exprtk_disable_return_statement macro for disabling return statements and associated exceptions at the source code level.
