Telemetry feedback with xyz incrementing
Added preprocessor directives to enable ROS wifi_bridge package to compile form
firmware sources.
preprocessor ifdefs so that wifi_bridge package can acces DFABridge messge types
Changed struct packing #ifdef variable from WIN32 to PACK_STRUCTS to make it compatible when compiling on linux
Topology Feedback feature (experimental)
Topology Feedback feature (experimental) compiles
Removed I2C for easier debugging and added topology feedback
Added .gitignore
Topology Feedback: one topology matrix entry at the time approach
Merged with linalgebra_fix and new folder structure
UART buffer extendend and made explictly cyclic.

There is still a bug when the rate of input to the buffer [Byte/s] is to high: 5000  [Byte/s] seems to be ok but 12'500 [Byte/s]  seems to be too much. This causes the UART buffer to fill faster than the UART Interrupt can send it to the bus. A warning in the comments and the lighting up of the RED led shows that something went wrong.
Shut off another IMU related command for esier debugging via JTAG.

Commands related to the IMU tend to block execution when the module is attached via JTAG.
Finalized UART fix.

- UART buffer is now explicitely cyclical in transmission (Tx)
- Size of UART transmission and reception buffers can be adjusted through defines in uart.h directly. Supports until 2^16 bytes in buffer length (practically the whole ram) per buffer (Rx and Tx)
Added defines for compatibiltity with DFAtool build
Topology feedback implemented

Note: topology has wierd values, the transmission mechanism was tested and was ok if other values were supplied. This could be a bug with the topology code.

Fixed linker issue when having the linalgebra_util.h header included in more than one file.

Description and explanation of the issue http://stackoverflow.com/questions/14855915/creating-global-variables-causes-linker-error
Added the TOP_SetRawElement() method with inclusion guards with ID "_ROS_DFA_TOOL"

This method is need by the DFA tool to set the Topology vector which is a "private" variable in the C code of the topology.
