switch sensitivity is functional

I am stunned and pleased to report that the switches finally respond to an appropriate amount of pressure in the shoe.

I experimented with several installations, padding, switch sizes and latches and now have the final implementation, which is made from medium size tape-switch samples.

After several iterations of back and forth, the following is functional:

-each heel segment has two switches which can distinguish between the front and back of the heel, with only a slight amount of pressure but at the same time no false positives, which is what I was finding before.

-each toe segment has four switches which can distinguish between right, left, front and back, again, with only a slight amount of pressure but no false positives.
