simple forex server that gets stuff with /latest
added way to record /latest into /rates
cleaned up rate dir
added protractor tests; some other things may still be broken in this commit
fixed test but still can't get json fixture to work and is commented out
modifying the forex text
including the node js server
connectd forex angular service to controller; added an update button, added 'oldcedi rate'. ForEx test still broken on json fixture
got rid of json fixture and fixed the tests on ForEx so they pass.  All good to merge to master
