Bookkeeping module

The math works very well.
However, it seems to also calculate in reverse often ending up with a value that is much more than 2 decimal places. Also, if there are no decimal places, it does not include them so $4.80 looks like 4.8
Otherwise, everything is beautiful in the calculations.

I am obsessed with accuracy. Changes is display may come later. Suggestions that change the display but not the value are welcome.

I stream lined the HTML and javascript. Also added the New Row button back in. I need to move on and incorporate this in to the project.
