/**
 * @brief Central manager for all connected aerial vehicles
 *
 * This class keeps a list of all connected / configured UASs. It also stores which
 * UAS is currently select with respect to user input or manual controls.
 *
 * This is the abstract base class for UASManager. Although there is normally only
 * a single UASManger we still use a abstract base interface since this allows us
 * to create mock versions of the UASManager for testing purposes.
 *
 * See UASManager.h for method documentation
