Basic handler routing

As you may recall, a URI path component determines the resource representation for a web application. Within the HTTP request message structure, not only do we have a target in the request line, but we also have the requested method as well. HTTP methods, or verbs, explain the intent of the request to act on the resource identified by the target. Within the realm of application development, the request method, in conjunction with the target resource identifier, will determine what application code the service is supposed to run. To this end, we will start by talking about how to add route mappings to your Echo project, and more importantly, how Echo uses the information in the request to run your handlers.
