Mueller and Müller (M&M) based clock recovery block with complex input, complex output.
This implements the Mueller and Müller (M&M) discrete-time error-tracking synchronizer.
The complex version here is based on: Modified Mueller and Muller clock recovery circuit Based: G. R. Danesfahani, T.G. Jeans, "Optimisation of modified Mueller and Muller algorithm," Electronics Letters, Vol. 31, no. 13, 22 June 1995, pp. 1032 - 1033.

Estimate input requirements given output request.
noutput_items | number of output items to produce |
ninput_items_required | number of input items required on each input stream |
Given a request to product noutput_items
, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.

ninput_items | number of input items available on each input stream |
