Detailed Description

Provides simple packet finder which may be consist of stx, etx, payload, ...

Note

Usage:

@code

Todo:

(1) getting buffer from this class
(2) simple construction of this class
(3) device abstraction
(4) extend-able packet structures
(5) like ros, auto-generation of code from scripts
(6) packetFinder to ros converter
(7) evaluate it (valgrind)
