Minimal debug/rep functionality

Correct, I'm currently trying to figure out how to ignore them (ie have it 
step "over" instead of "into" standard library calls (in particular, the 
linecache.getline(foo, x) call).

Also, I had quite a time figuring out the damn name for what I was trying to 
do.  My first thought was implementing a REP loop of my own.  Then I 
started looking at the debugging code.  Finally, I was put on the correct 
trail by looking at "tracing".

Yup, for now I simply need to look at traces.  Speed is not important (1. 
this is a prototype and 2. speed may never be important).  Further, I'm 
only looking at single function (aside from library function calls) 
algorithms for the moment.

Thanks for the input.
