Add some sample code for ParseData.cpp under Linux

[HTLife]

Add examples:

1. Example CMakeLists.txt for building ParseData.cpp under Linux environment.
2. Setup sensor before receiving data.

Under windows env, the ParseData.cpp work fine, since LORD provide MIP Monitor GUI to setup sensor. However, we don't have any GUI tool to setup Inertial sensor message. I think it would be more clear if we add the setup code to the ParseData.cpp example. Then user won't getting confused that sensor didn't output anything on screen.
