New piecewise package in development

Hi,

I have responded to requests made regarding my first release.  This is a work in progress, so be patient.  I will be 
making periodic releases to the list of pw.mac as it grows and gets more useful.  I do plan to support this and I intend 
to follow up with updates.  I have many things I would like to add.

Anyway, this is not an upgrade to include new functions.  It is just the same thing with the source code cleaned up, 
which has been requested.  Again type pwhelp() for information on this package.  Also see my previous emails.  I have 
attached three examples.  Two fourier series applications and one with simple plots.  There are two of each, one for 
wxMaxima and one for XMaxima and command line Maxima.

Thanks,

Rich
