import "github.com/mgutz/str"
Package str is a comprehensive set of string functions to build more Go
awesomeness. Str complements Go's standard packages and does not duplicate
functionality found in strings or strconv.
Str is based on plain functions instead of object-based methods, consistent with Go standard string packages.
str.Between("<a>foo</a>", "<a>", "</a>") == "foo"
Str supports pipelining instead of chaining
s := str.Pipe("\nabcdef\n", Clean, BetweenF("a", "f"), ChompLeftF("bc"))
User-defined filters can be added to the pipeline by inserting a function or closure that returns a function with this signature
