Projecting Week and Day boxes forward into the future, as an aide in framing the shape/profile of the coming week(s)/day(s).

~input number of 2week blocks or number of 2day blocks to project forward.

////notes////
-I have limited the project-forward numbers to keep it neat. If you want to play around with them, edit UP the FIRST integer in lines 56, 58, 62, 64 (currently set to 11,10, 41, 40 respectively). And edit UP maxvals in lines 9 and 15.
-To change the height of weekly and/or daily boxes, tweak the SECOND integer in lines 56, 58, 62, 64.
-Written for ES (S&P); tested/working on FX and BTC too.
-Starts painting/Resets at the beginning of a new week (i.e. Sunday eve).
-Sunday is blended into Monday; day's are defined as finishing at 6pm (New York Time).
