Convolutional encoder simulation

Use this to convolutionally encode bit sequences of any length. It takes the bit sequence and constraint length as input. It returns the encoded sequence and the generator polynomial used to encode which is obtained from the constraint length.

Convolutional coder generates redundant bits using Modulo 2 additions. It can be viewed as a finite state machine that consists of a number of shift register stages.
