Commit 4 -- script proven and onto actual sample learning

I have tested the concept of replacing code between this update and the
prior commits; it's my fault
for not uploading them, well. As such, I've decided to move forward with
a skeleton of the concept:
starting with introductory problems, chapters, etc.

As such, the lessons will now have their own individual keys to check
for,
and possibly their own script, since the object is to develop a way to
slowly change to actual programming. The script will remain for now, to
try and keep some
semblence of consistency between the functions.

I've added:
> a lesson_list file, which contains the lesson functions (which will
display the
lessons themselves, as well as the subfunctions for the problems
therein).

> save_date text and py; save_data.txt saves the actual data for the
student,
such as name, current chapters, and an array which saves the answers for
prior
problems, to allow for it to serve as a reference. As of the moment,
it's an
array but it will be a dictionary once I feel like doing that. The
python file
actuates all of that.

I've removed:
> test files; they're unnecessary as the test files will now be the
lesson
functions themselves.

I've modified:
> main(); it has now been modified to support an IDE as the main
interface, since
I have no idea how to make it look all fancy. Once I have more of a
proof-of-concept,
I'll look into recruiting a designer or new-media type. Whoever would
love to help out!
