     * Add a new detector to the list of detectors that a request can use.

     *
     * ### Environment value comparison
     *
     * An environment value comparison, compares a value fetched from `env()` to a known value
     * the environment value is equality checked against the provided value.
     *
     * e.g `addDetector('post', array('env' => 'REQUEST_METHOD', 'value' => 'POST'))`
     *
     * ### Pattern value comparison
     *
     * Pattern value comparison allows you to compare a value fetched from `env()` to a regular expression.
     *
     * e.g `addDetector('iphone', array('env' => 'HTTP_USER_AGENT', 'pattern' => '/iPhone/i'));`
     *
     * ### Option based comparison
     *
     * Option based comparisons use a list of options to create a regular expression. Subsequent calls
     * to add an already defined options detector will merge the options.
     *
     * e.g `addDetector('mobile', array('env' => 'HTTP_USER_AGENT', 'options' => array('Fennec')));`
     *
     * ### Callback detectors
     *
     * Callback detectors allow you to provide a 'callback' type to handle the check. The callback will
     * receive the request object as its only parameter.
     *
     * e.g `addDetector('custom', array('callback' => array('SomeClass', 'somemethod')));`
     *
     * ### Request parameter detectors
     *
     * Allows for custom detectors on the request parameters.
     *
     * e.g `addDetector('requested', array('param' => 'requested', 'value' => 1)`
     *
     * You can also make parameter detectors that accept multiple values
     * using the `options` key. This is useful when you want to check
     * if a request parameter is in a list of options.
     *
     * `addDetector('extension', array('param' => 'ext', 'options' => array('pdf', 'csv'))`
