 * @author dan

 *

 *    Create a program and submit in schoology.

 *    Requirements

 *    use 2 d arrays to store your grades

 *    You should have 7 school classes/periods

 *    within those classes each should have 4 formative grades and 3 summative grades

 *    for a total of 49 data points.

 *    i.e. period 1 formative grade of 85

 *    Calculate weighted average score by class then you can also then calculate average score for all classes.
