0.9.1   Added THREE (3) high-level functions: MtrAddRdeviceTop(), MtrAddRdeviceInit(), MtrAddRdeviceDeinit(). These functions call MtrAddRTop(), MtrAddRInit() and MtrAddRDeinit() respectively. However, there are NO changes to MtrAddRStart(), hence there is NO associated function MtrAddRdeviceStart().
            Removed parameter "name.str" from MtrDeviceWriterStr(), as its mandatory name is "mt4Rdevice". Todo: (a) test function "mt4RdeviceEval()" in MetaTrader.
