Mezzo Versions Save

Added

• Live playback on the terminal: Mezzo compositions can now be played back live from the terminal using an external midi synthesiser (e.g. SimpleSynth) and Euterpea.
• Empty cadences: you can use end as a cadential phrase to compose a chord progression without a cadence.
• Score transformation: you can use the functions such as delay and transpose to manipulate music at the MIDI track level. While this allows for more flexibility, composition of Scores is not rule-checked, so there is no static guarantee that the resulting music will sound good.

Changed

• The melody constructor play has been renamed to start.

Fixed

• Readme typos and rule set changes in examples.
• Clashes with Prelude's min function.

First more-or-less complete, public release of Mezzo.
