/**
 * Base class for all tracker RequestProcessors. RequestProcessors handle and respond to tracking
 * requests.
 *
 * ## Concept: Request Metadata
 *
 * RequestProcessors take a Tracker\Request object and based on its information, set request metadata.
 *
 * Request metadata is information about the current tracking request, for example, whether
 * the request is for an existing visit or new visit, or whether the current visitor is a known
 * visitor, etc. It is used to control tracking behavior.
 *
 * Request metadata is shared between RequestProcessors, so RequestProcessors can tweak each others
 * behavior, and thus, the behavior of the Tracker. Request metadata can be set and get using the
 * {@link Request::setMetadata()} and {@link Request::getMetadata()}
 * methods.
 *
 * Each RequestProcessor lists the request metadata it computes and exposes in its class
 * documentation.
 *
 * ## The Tracking Process
 *
 * When Piwik handles a single tracking request, it gathers all available RequestProcessors and
 * invokes their methods in sequence.
 *
 * The first method called is {@link self::manipulateRequest()}. By default this is a no-op, but
 * RequestProcessors can use it to manipulate tracker requests before they are processed.
 *
 * The second method called is {@link self::processRequestParams()}. RequestProcessors should use
 * this method to compute request metadata and set visit properties using the tracking request.
 * An example includes the ActionRequestProcessor, which uses this method to determine the action
 * being tracked.
 *
 * The third method called is {@link self::afterRequestProcessed()}. RequestProcessors should
 * use this method to either compute request metadata/visit properties using other plugins'
 * request metadata, OR override other plugins' request metadata to tweak tracker behavior.
 * An example of the former can be seen in the GoalsRequestProcessor which uses the action
 * detected by the ActionsRequestProcessor to see if there are any action-matching goal
