code: def render(template, &block)
           frmt = params['format'.freeze] || 'html'.freeze
           mime = nil
           ret = ::Plezi::Renderer.render "#{File.join(::Plezi.templates, template.to_s)}.#{frmt}", binding, &block
           response[Rack::CONTENT_TYPE] = mime if ret && !response.content_type && (mime = Rack::Mime.mime_type(".#{frmt}".freeze, nil))
           ret
        end
docs: 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" }
