/**  
 *  A simple ReadFile Class where It will take the input as a redirection from any csv file 
 *  so i won't need to tie it down to one particular file, i can just process any file 
 *  with a redirection.  
 * 
 *  @author Freeman Lo
 *  @version 0.0.1 Build 1 April 1, 2014.
 *  Limitations - next time, i will do FILE I/O through as an argument from main instead of file redirection.
 *  Sadly enough, i seem to always do file input with all my java code with file redirection
 *	Python code on the other hand, i have never done file redirection but i've done hardcode open file and from arguments
 *  i need to reverse the order sometimes.
