started putting together class for sensors

will make accessing data much easier
made header file for SBoard

will support functions to:
    - read in data
    - write data to serial port
finished adding private methods
added struct for sensors

will make reading data clean and easy
... sweeet
added stuff to be able to control pins

NOTE: not implemented yet
finished: should have full functionallity

outstanding: testing
everything compiles (yay)
