CSE 142 Winter 2008, Marty Stepp

This program reads an input file of data about students' attendance in
section and outputs the attendance, points earned, and grade percentages for
each student in each section.

The format of the input file is explained in the Ch. 7 lecture slides.

Example line of input from the file, sections.txt:
111111101011111101001110110110110001110010100

Example output for the above line:
Sections attended: [9, 6, 7, 4, 3]
Student scores: [20, 18, 20, 12, 9]
Student grades: [100.0, 90.0, 100.0, 60.0, 45.0]
