Renders the requested template (should be a string, subfolders are fine).

 Template name shouldn't include the template's extension or format - this allows for dynamic format template resolution, so that `json` and `html` requests can share the same code. i.e.

       Plezi.templates = "views/"
       render "users/index"

 Using layouts (nested templates) is easy by using a block (a little different then other frameworks):

       render("users/layout") { render "users/index" }
