tool for identifying LilyPond grobs

Currently, my greatest problem is to identify grobs so that I can
modify their properties.

I suggest a tool `grob' which accepts a LilyPond code fragment (either
as an argument to the tool or read in interactively using
e.g. readline), returning the context and grob.


  grob a_"foo"

should return something like this:

    `a': `Staff.NoteHead'
    `"foo"': Staff.TextScript

In case this isn't possible, I suggest to add a \what keyword to
LilyPond which emits information on its argument to stdout (but having
no other effect):

  \what a_"foo"

The trial-and-error method which is necessary at the moment due to
lacking documentation costs way too much time.
