Ability to create/update number/string/boolean variables Query state of variable + change events to reflect values in UI.

@pelikhan, @mmoskal: I think that VM variables should be statically typed since we are going to very low resource MCUs.

pelikhan commented 3 years ago

In blockly, it's boolean, number or string, which should be inferred from the first use. I would argue that we don't need to have diferrent numberic types here. We have precise number types in jacdac to minimize packets on the bus, but at the VM level, we should only support a float.

OK. I will set type based on first use and then raise an error if there is a dynamic type error.
