oops forgot to add the changes
used dataTables javascript library <http://datatables.net/index> to add functionality to the rankings table (as well as make it look nice).  Data can dynamically be sorted by both country name and value, a search is included, and number of countries shown at one time can also be specified.  Visuals might need to be updated to match rest of page, and I want to include functionality to choose year of data (right now just shows 2011 data)
forgot to add dataTables library
removed placeholder rankings text in index.html
added the ability to select by year.  Currently a drop down menu, maybe check boxes would be better?
some formatting to keep column widths constant and to make the overall table easier to read (less wide)
added placeholders for 'income group', to be improved upon further.  Added new stylesheet for the table to better match the current styling, specifically on index.gain.org/ranking
color-coded the values to align on a green->yellow->red gradient.  Jon and I thought it would be more useful to then see all years at once, so table was modified to show all years, and the 'year' selector' was removed (along with accompanying functions
added placeholders for thresholds
