Added StudentData class

currently it stores what countries and continents they’ve looked and
their name
Further StudentData work

Added a few more utility functions to StudentData.
MapPanel now uses StudentData to store data on what’s been looked at
and expects a StudentData object as an argument to the constructor
Add Health/Economic split to StudentData

StudentData now keeps track of what was seen in each mode separately;
functions have been modified accordingly
