 * Project Num : Project 1
 * Purpose     : To take a list of grade values from an external file and parse it
 *             : so that it will find out the mean or average value and compare it with
 *             : other scores to find out the Letter Grade for each student.
 * Algorithm   : OO programming with two classes; an input file, an output file
 *             : The average section where compute and assign letterGrades each are computed at O(n)
 *             : My read-in and output methods are also at O(n)
 *             : A read File method to take in value from a file
 *             : A method to Compute the mean of all of the scores from file
 *             : A method to gather the Letter grade for each scores
 *             : A final method to print out each of the scores and its letter grade value
 *             : An arraylist was used to capture all of the scores then process letter grade
 *             : Project1Driver.java (Main); AssignScore.java (library)
 * Compile     : javac Project1Driver.java
 *             : java Project1Driver < data.txt
