implemented independent colours and file import 

managed to implement csv parsing methods that create and populate a
hashtable in which the key is represented by the country and the value
is an ArrayList of double in which we store the value for each of the 6
categories we have for the respective country in the csv file

also managed to figure out how to create each bar of a different colour 

none of these two though can be tested against the csv file because
moodle is not available and i cannot get the WHOdata.csv
