Comment:

 I attached a new patch, in which the new function is called 'firwin2'.
 The calculation is basically that same as in the code submitted by tash,
 but I've rewritten parts, and used different variable names and
 conventions.  I've included tests, and updated other relevant doc files.

 (When I added firwin2 to fir_filter_design.py, I also changed other code
 in that file so that the variable holding the number of taps was
 consistently called 'numtaps'.)
