Yes, I received a time of 00:00:00.0156250

Yes, in Python there are a couple of variable objects like "fw_edges"
that grow into "<huge dict 0x12ad810>" etc (but to me they resemble
more like IronPython List object).

Yes.

Recently, I have been using an imported py file. I am about to start
testing using the console. I have been using a custom Progressbar
Form to notify the user of what was happening but I might try using a
console for the same concept to see if it is any faster.

This is good to know but not always ideal. I am trying to write a
Class Library to so any app can use it.
