Express utility functions

The pillarjs GitHub organization contains a number of modules for utility functions that may be generally useful.

Utility modules	Description
cookies	Get and set HTTP(S) cookies that can be signed to prevent tampering, using Keygrip. Can be used with the Node.js HTTP library or as Express middleware.
csrf	Contains the logic behind CSRF token creation and verification. Use this module to create custom CSRF middleware.
finalhandler	Function to invoke as the final step to respond to HTTP request.
parseurl	Parse a URL with caching.
path-match	Thin wrapper around path-to-regexp to make extracting parameter names easier.
path-to-regexp	Turn an Express-style path string such as ``/user/:name` into a regular expression.
resolve-path	Resolves a relative path against a root path with validation.
router	Simple middleware-style router.
routington	Trie-based URL router for defining and matching URLs.
send	Library for streaming files as a HTTP response, with support for partial responses (ranges), conditional-GET negotiation, and granular events.
templation	View system similar to res.render() inspired by co-views and consolidate.js.
