Feature: Number and Arithmetic blocks

[valentijnnieman]

It would be real nice to have blocks that are just numbers, and blocks that do arithmetic on those numbers. i.e. blocks that just outputs whatever number you put in, say "220" and "110", and you can connect those numbers to arithmetic blocks, say "+", and it will add them together. You could then output the result "330" to a Oscillator block's frequency input, for example. If you're familiar with languages like Max/msp (which is a big inspiration) this won't be anything new or shocking :-)

One thing I am thinking about if this will make it too complex. I always thought of Curve as being a tool for people to learn about synthesis, so adding numbers might make the learning curve too steep. If we didn't have numbers, Curve could just be seen as a stepping stone to learning more complex stuff like Max/msp.
