added new shcool calendar template - esolved conflicts

Hi Donna Stuart,

Here is a new template I added. Let me know if you think this is too big of a PR. It was just a full days worth of work so not sure if you would want me to do multiple PR in one day. 

Donna, Im using GSAP to animate the background. It is very smooth on my computer and also on most of our chrome boxes. However I noticed that on the 4k screen it is very jumpy. It may just be a hardware limitation but if you see anything that could be changed to increase performance let me know. I believe you've used GSAP before for widgets.

Thanks,
Mat
