Install
make code more explicit

use better coding style.
remove deprecated lab
include files

Include source files.
fix typo

fix syntax error
fix spacing

dedented entire file.

The unnecessary indentation was messing up the code environments.
more explicit string formatting

updated code to better coding style.
include code from source files instead
make code compatible with Python 2.7

Removed unneeded import (only integer division was performed).

Also removed parenthesis from the print statement.  Since all the labs
are still Python 2.7, the syntax is bound to get some puzzled looks from
students.
remove forced positioning from figure
remove locals from string format

Use explicit variable names instead.
