I designed a pretty coolbath tub, here are the updates for today:

-fixed a math error on the cold water spout code.
-fixed general water heat averageing code.
-wrote general water loss for bath tub ( heat/(volume * 3) so far )
-wrote the water spout code for boiler.

Still have to add code for the cold water spout of the bath tub and ability to flush it.

Have to work on the bath salts.
