Function list

Go functions have a unique naming style. One, who has experience in other language but new in Go, may have difficulties to find out right string function to use.

Here is a list of functions in strings and xstrings with enough extra information about how to map these functions to their friends in other languages. Hope this list could be helpful for fresh gophers.
