Middleware:

The middleware is exposed to the developer through the BuildChain() or DefaultChain() methods.

These methods expose a context chain, which you can then use or expand on wherever a context chain is required.

A chain has the following life-cycle:

(Boot-up)

Resolve: Resolve(route, action) called; (type checking here.)
Hooks may be injected here; they receive raw reqs & responses.
- Hooks op at the req/response level.
- Hooks can be executed at any point in the Request lifecycle.
- Hooks act as additional middleware extensions that apply for a specific route.
Returns a HandlerFunc().
- Prepares a request-facing (Controller,Action) pairing for the route.
- Which routes the request through the (BeforeAttach) hooks.
- Attachs context chains to the (Controller)
- Routes the request through the (AfterAttach) hooks.
- Executes Controller.Action()
- Routes the request through the AfterExecution hooks.

(Request)

BeforeAttach :: action is readied, chains are unattached
AfterAttach :: chains attached, action pending invocation.
AfterExecution :: controller has executed its action(s)

Default Hooks:

Resolve ::
BeforeAttach :: request logger, panic logger
AfterAttach :: nothing
AfterExecution :: responder

Perf Hooks:

BeforeAttach :: perf_start
AfterAttach :: perf_step
AfterExecution :: perf_stop

Debug Hooks:

BeforeAttach :: panic printer, enable lib/web debug flags.
