pw.mac 2.1

Hi All,

Here is a link to a new pw.mac for piecewise functions.  It now uses signum functions by default but you can optionally change it 
back to unit_step().  There are rules defined for integrating and differentiating the unit_step(), diracdelta() and signum() 
functions so you can do Fourier transforms mainly of piecewise functions.
