/**
 * Base Page Controller
 *
 * 1. The page controller checks the evaluated route parameters to determine the
 *    appropriate action.
 * 2. The action modifies and gets all of the required data from the model classes.
 * 3. The controller then pushes the data to the appropriate view for the action and
 *    result.
 * 4. The controller finally renders the view output and returns it to vB for
 *    output.
