-Goroutine local storage
-
-### IMPORTANT NOTE ###
-
-It is my duty to point you to https://blog.golang.org/context, which is how 
-Google solves all of the problems you'd perhaps consider using this package
-for at scale. 
-
-One downside to Google's approach is that *all* of your functions must have
-a new first argument, but after clearing that hurdle everything else is much
-better.
-
-If you aren't interested in this warning, read on.
-
-### Huhwaht? Why? ###
-
-Every so often, a thread shows up on the
-[golang-nuts](https://groups.google.com/d/forum/golang-nuts) asking for some
-form of goroutine-local-storage, or some kind of goroutine id, or some kind of
-context. There are a few valid use cases for goroutine-local-storage, one of
-the most prominent being log line context. One poster was interested in being
-able to log an HTTP request context id in every log line in the same goroutine
-as the incoming HTTP request, without having to change every library and
-function call he was interested in logging.
-
-This would be pretty useful. Provided that you could get some kind of
-goroutine-local-storage, you could call
-[log.SetOutput](http://golang.org/pkg/log/#SetOutput) with your own logging
-writer that checks goroutine-local-storage for some context information and
-adds that context to your log lines.
-
-But alas, Andrew Gerrand's typically diplomatic answer to the question of
-goroutine-local variables was:
-
-> We wouldn't even be having this discussion if thread local storage wasn't
-> useful. But every feature comes at a cost, and in my opinion the cost of
-> threadlocals far outweighs their benefits. They're just not a good fit for
-> Go.
-
-So, yeah, that makes sense. That's a pretty good reason for why the language
-won't support a specific and (relatively) unuseful feature that requires some
-runtime changes, just for the sake of a little bit of log improvement.
-
-But does Go require runtime changes?
-
-### How it works ###
-
-Go has pretty fantastic introspective and reflective features, but one thing Go
-doesn't give you is any kind of access to the stack pointer, or frame pointer,
-or goroutine id, or anything contextual about your current stack. It gives you
-access to your list of callers, but only along with program counters, which are
-fixed at compile time.
-
-But it does give you the stack.
-
-So, we define 16 special functions and embed base-16 tags into the stack using
-the call order of those 16 functions. Then, we can read our tags back out of
-the stack looking at the callers list.
-
-We then use these tags as an index into a traditional map for implementing
-this library.
-
-### What are people saying? ###
-
-"Wow, that's horrifying."
-
-"This is the most terrible thing I have seen in a very long time."
-
-"Where is it getting a context from? Is this serializing all the requests? 
-What the heck is the client being bound to? What are these tags? Why does he 
-need callers? Oh god no. No no no."
-
-### Docs ###
-
-Please see the docs at http://godoc.org/github.com/jtolds/gls
-
-### Related ###
-
-If you're okay relying on the string format of the current runtime stacktrace 
-including a unique goroutine id (not guaranteed by the spec or anything, but 
-very unlikely to change within a Go release), you might be able to squeeze 
-out a bit more performance by using this similar library, inspired by some 
-code Brad Fitzpatrick wrote for debugging his HTTP/2 library: 
-https://github.com/tylerb/gls (in contrast, jtolds/gls doesn't require 
-any knowledge of the string format of the runtime stacktrace, which 
-probably adds unnecessary overhead).

-// Package require implements the same assertions as the `assert` package but
-// stops test execution when a test fails.
-//
-// Example Usage
-//
-// The following is a complete example using require in a standard test function:
-//    import (
-//      "testing"
-//      "github.com/stretchr/testify/require"
-//    )
-//
-//    func TestSomething(t *testing.T) {
-//
-//      var a string = "Hello"
-//      var b string = "Hello"
-//
-//      require.Equal(t, a, b, "The two words should be the same.")
-//
-//    }
-//
-// Assertions
-//
-// The `require` package have same global functions as in the `assert` package,
-// but instead of returning a boolean result they call `t.FailNow()`.
-//
-// Every assertion function also takes an optional string message as the final argument,
-// allowing custom error messages to be appended to the message the assertion method outputs.
