/** Dialog for building a MIDI note transformation.
*
* This can build transformations with any number of operations, but is limited
* in power and can't build arbitrary transformations since there is no way to do
* conceptually parenthetical things (i.e. push things to the stack).
*
* With this, it is possible to build transformations that process a single
* value in a series of steps starting with a seed, like: "value = seed OP
* value OP value ..." where OP is +, -, *, or /, left associative with no
* precedence. This is simple and pretty clear to the user what's going to
* happen, though a bit limited. It would be nice if the GUI could build
* fancier transformations, but it's not obvious how to do this without making
* things more confusing.
