Example of a buffered file reader using a buffered scanner.

bufferedScanner.java

/**
 * Extracts comma separated values from an external file. The method readObjectData() 
 * expects to find employee data on each line separated by a comma. The pattern example outlined here:
 *    
 * String,int,String,int
 * String,int,String,int
 *    
 *    The above csv inputs are returned by Scanner as:
 *    - Name of employee (String)
 *    - Years employed (int)
 *    - Employee prodict code (String)
 *    - Number of sales (int)
