A Costas loop carrier recovery module, great for synchronizing to BPSK, QPSK, and 8PSK.  The Costas loop locks to the center frequency of a signal and downconverts it to baseband.

* When order=2: used for BPSK where the real part of the output signal is the baseband BPSK signal and the imaginary part is the error signal.
 
* When order=2: used for BPSK where the real part of the output signal is the baseband BPSK signal and the imaginary part is the error signal.
 
* When order=4: can be used for QPSK where both I and Q (real and imaginary) are outputted.
