Adding basic FIR filter.  Still somewhat untested.
Cleaned up the implementation for better testing.  Added low-pass filter.  Added better input signals.
Adding linear phase fir filter designs.
First running version of the linear phase fir filter.  Not working correctly.
Updated the basic fir-filter design to be more likely to infer into a DSP slice.
Got a design of the linear-phase fir-filter working.  Tested with the Chirp input, produces results similar to the basic fir-filter.
Added a sparse FIR filter implementation.
Added a pass-through coefficient set, identical in length as the low-pass.
Updated the design of the clock-generator.  Now multiple clock generators will be phase-aligned by design.
Adding a signal multiplexor and demultiplexor. Provided phase-aligned clocks, the delay through both modules (back-to-back) is 2 clk clock cycles.
Got a simulating draft of a multichannel filter running.  The filter-tap still needs updating to meet the needs of this filter design.
The multichannel fir filter works for a static filter.
