/**
* Routes the HTTP request into a Destination instance.

*
* The process of routing the request is as follows:
*
* <ul>
* <li>
* Checks if the type of the request matches.
* </li>
* <li>
* Checks the structure of the path, see if it matches
* the structure provided by the pattern.
* </li>
* <li>
* Checks individual placeholder rules in the pattern,
* while also creating argument replacement array
* {@see $argsPlaceholderReplacements}.
* </li>
* <li>
* If everything matches, construct the Destination
* instance to be returned.
* </li>
