Added local() to request

[coopernurse]

Hi there,

express is cool. I'm writing an app that uses route chaining via next(). I didn't see an obvious way to set state on the request so that my first route handler could set a variable that I could reference in subsequent handlers.

I added a local() function on request for this. It's similar to param() but only gets/sets variables that you define.

Not sure if this is a patch more appropriate to add to Connect, but let me know what you think.

Tests included.

thank you!

typically you just put props like that right on req, but you will have the same potential namespacing issues

[coopernurse]

ah, I see. do you see value in providing a "local" namespace for this? Could help prevent folks from accidentally clobbering reserved slots on req. If not, perhaps I'll revert this patch and simply add some notes to the express docs explaining that you should hang stuff directly off req. As a node/connect/express newb I didn't realize that was how you do it.

I would rather them be on req, as long as people are careful with their naming

[coopernurse]

Ok. I'll close out this pull request and take a look at the express docs and perhaps add an example for this. thank you.

sounds good thanks :)
