+* Add custom motor record driver (asynMotor) implementation in order to improve realtime performance    
+    * added iocsh commands (same syntax as EthercatMC):
+       1. ecmcMotorRecordCreateController(portName,         // Asyn port name for asyn com with ecmcMotorRecord
+                                          MotorPortName,    // Not used. Kept to keep syntax same as EthercatMC
+                                          numAxes,          // Not used. Kept to keep syntax same as EthercatMC
+                                          movingPollPeriod, // Poll period when moving [ms]
+                                          idlePollPeriod,   // Poll period when idle [ms]
+                                          optionStr)        // Options (execute "ecmcMotorRecordCreateController" in iocsh to see available options)
+       2. ecmcMotorRecordCreateAxis(controllerPortName,     // Same as portName for controller
+                                    axisNo,                 // Axis index
+                                    axisFlags,              // Options mainly for powering axis.
+                                    axisOptionsStr)         // Options (execute "ecmcMotorRecordCreateAxis" in iocsh to see available options)
+    * Note: EthercatMC is still supported and can be used like before
