This commit moves almost all of the template functions into separate packages under tpl/ and adds a namespace framework. All changes should be backward compatible for end users, as all existing function names in the template funcMap are left intact. Seq and DoArithmatic have been moved out of the helpers package and into template namespaces. Most of the tests involved have been refactored, and many new tests have been written. There's still work to do, but this is a big improvement. I got a little overzealous and added some new functions along the way: - strings.Contains - strings.ContainsAny - strings.HasSuffix - strings.TrimPrefix - strings.TrimSuffix Documentation is forthcoming. Fixes #3042
