Starting experimenting with a new ProgressGenerator class.  This is intended to read a buffer from the input and feed to to the output while yielding the progress percentage.
Starting experimenting with a new ProgressGenerator class.  This is intended
to read a buffer from the input and feed to to the output while yielding
the progress percentage.

It is just an experiment because it is intended to be generic enough to work
with several input and output types.  Currently, it needs an open file
object as input and a SAX parser as output.
