This a framework to test new ideas in transmission technology. Actual development is a LDPC-coder in

random
------

 Produces uniform random-numbers in the range 0-255. The random-number
generator is based on a simple polynomial, so it's not really high-class.
 The seed may be set to a positive number, so that subsequent tests yield
the same random numbers. This is useful in testing environments.

outputs:
	U8

Config:
	mode<int>: 0
		0 -> normal operation
		1 -> on every call the seed is reset. This is useful if one wants
		to do measurements and needs the same data on sending and receiving
		side

	seed<int>: 0
		If seed < 0, the actual timer is taken for it's initialisation,
		else the random-generator is initialised using seed.
		The second case is useful for testing purposes
