Added event activations in the main thread to avoid getting stuck when an scanning error occurs or the scan is cancelled.

Solved a problem when starting a new scan when the previous one was stopped. The new one never started.

Added a module to test the new firmware for AX12 servos.

Increased the speed of the ping() function.

Added two dynamixel server implmentations: one with the FTDI and the other one with a standard serial port.
Added a new configuration file with specific information for each implementation.
Changed the examples and the configuration files accordingly.

Added a synchronization procedure in the dynamixel server to avoid problems at first power up.

Solved a problem in the reception,when invalid data is received in front of the expected packet. Both in the server and the modules.

Solved a bug in the get_device() function. The function get blocked when no device was found with the desired id.

The new serial number is compared with the previous one to avoid reinitializing the same bus over and over.

Added support to get dynamixel converters from the serial number instead of the usb index, which is more robust.
Previous API using the usb index is still supported.

Changed the config_bus function to change only the communication device baud speed, but not that of the devices connected to the bus. 

The set_bus_id() function has been move to the protected class. 

Solved some memory leacks.

Modified the main CMakeLists.txt to set the compiler flags for the C++ compiler instead of the C compiler.
Solved some compilation warnings that appeared.

Modified the dynamixel server to be able to free the used devices when the associated CDynamixel object is destroyed.

Minor changes in the get_device() function to avoid multiple instances of a single dynamixel device.
