Midiutil

* Fairly major restructuring of the code contributed by meteorsw, including:
* Removing the MIDIEvent class and subsuming functionality in GenericEvent
and derivative classes.
* Allowing for the specification of times in MIDI ticks, as well as quarter
notes.
* General clean-up and restructuring. Logic on how an event serializes itself
to the MIDI stream is now associated directly with the object.
* Renaming of some variable to be less confusing to users.
* Placing comparison operators in the derived classes of GenericEvent, where
they really belong.
* Addition of channel pressure event.
* Clarifications on documentation.
* Added pitch bend support with `addPitchWheelEvent`.

Date: 6 March 2017

A code clean-up release. Not much in the way of new features.

* Documentation changes, typo corrections, etc.
* Simplify the importation of the library. It's now possible to just:

from midiutil import MIDIFile

which seems somewhat easier.
* Some formatting and cleanup work (PEP-ish stuff).
* Added Python 3.6 testing/support.
* Removed support for Python 2.6. All good things eventually come to an
end

Date: 28 September 2016

* Just a couple of typo's corrected (what's a "but fix" anyway?),
and the display of README.rst on Pypi.

* Allow for the specification of either MIDI format 1 or 2 files.
Note that in previous versions of the code the file being
written was format 2, but it was identified as format 1.
This error has been corrected. The default format for the file
is 1, which is the most widely supported format.
* Increased test coverage.
* Fixed bug in MIDIFile for `adjust_origin` = `False`
* Added ability to order RPC and NRPC sub-events in time, as
a work-around for sequencers that aren't good about preserving
event ordering for events at the time time.
* Updates to documentation.
* Added Travis CI to the build process. Verifying operation
on python 2.6 - 3 development version.
* Functions added:
* `addTimeSignature()`
* `addCopyright()`
* `addText()`
* `addKeySignature()`

Date: 23 September 2016

* Minor updates to build system so that code can be hosted at
Pypi (https://pypi.python.org/pypi/MIDIUtil/).

Date: 23 September 2016

* Code ported to GitHub
* Extensive updates to documentation, ported to Sphinx.
* Added ability to *not* adjust the MIDIFile's time origin.
Default behaviour is maintained, but will change in a future
version (by default the origin is currently adjusted).
* Changed the controller event parameter names to make them
clearer.
* Added support for Registered and Non-Registered parameter
calls (``makeRPNCall`` and ``makeNRPNCall``).
* General refactoring and clean-up.
* Added function to select tuning program and bank.
Some synthesizers, such as fluidsynth, require that
uploaded tunings be explicitly assigned to a channel.
This can be used after ``setNoteTuning`` in such a
case.
* Completed port to Python 3 / Unification of code base.
Support for python < 2.6 has been dropped so that the
Python 2 and 3 codebases could be unified.
* Changes the way that sorting works, simplifying it and making
it more expressive. The primary sort is on time; secondary on
ordinality for the event (which is user-definable, but defaults
to an ordinality for the class); and the
third is the order in which the events were added. Thus
is becomes easier to, say, make an RPN call, which entails
and ordered series of control change events all occurring at the
same time and of the same type.
* Added 'annotation' as a parameter to note addition function.
This can be used to attach an arbitrary python object to the
note event. This is useful for extension development.
