Compiles a pattern. Patterns may consist of literals, escaped
characters, wildcards (*) and parameters (:name). The syntax is
very similar to to Clout (https://github.com/weavejester/clout).
That's no surprise, because the code is similar too :)

Tests if request is matching the pattern associated to route.
Returns a map containing path, query and matched parameters on
success.

Returns a function that takes a request map as argument. The function
evaluates body and returns the value of the expression if pattern is
matching the request path. Parameters are bound to vars.

Example:
  (route
   "/blog/posts/:id"
   [id]
   (get-post id))

Use the :as keyword to assign the entire request map to a symbol.

Example:
  (route
   "/blog/:category/search"
   [category :as req]
   (search-category category (:query req)))

Returns a function that takes a request map as argument. The function
evaluates the body of the first route matching the request path and
returns the value of the expression. Parameters are bound to vars.

Example:
  (routes
   ("/blog/posts/:id"
    [id]
    (get-post id))

   ("/blog/:category/search"
    [category :as req]
    (search-category category (:query req))))
