* @brief The ResourceParameters provide access to the parameters passed in the URI.
*
* There are two types of parameters: Path parameters and query parameters.
*
* Path parameters are the values that fill the asterisk placeholders in the route
* definition of a ResourceNode.
*
* Query parameters are the key-value pairs after a question mark which can be added
* to each request, either by specifying them manually or as result of submitting an
* HTML form with a GET as method property.
