Easily enter music expressions in markup

Sometimes it is necessary to add a simple snippet of music into a markup function. Constructing the different notation elements manually can be painful, because of lots of trial-and-error positioning. The \ezscore markup command takes the pain out of manually constructing these music expressions in \markup mode.

When this command is useful: Basically, \ezscore is a wrapper for the \score markup command that puts everything on a RhythmicStaff, but automatically removes the staff-line, clefs, and time-signatures. Why use it? Because it utilizes LilyPond's built-in layout/spacing algorithms, so you can add any other overrides you want, which makes it possible to do things like compressing/expanding the horizontal spacing of notes with \newSpacingSection.
