4.0.0: Cycle Unified

Migrates to the Cycle Unified approach: the code is now written directly in xstream and adapts as necessary to other stream libraries.

3.1.0: Actions

• Fixed a bug where sources was passed to the default model instead of actions
• Pass the actions to the catch if useful/needed

3.0.0: Simplify interface

The pedal option defaultCatch was removed in place of defaultGear.catch to match model/intent defaults.

2.0.0: Catch

Add a model catch to gears

Promotes the idea of a catch directly on top of the model (between the
model and its teeth) to a first class citizen. This should make it much
easier to keep from having "stuck transmissions".

The default catch is simply a throw, so behavior should be the same, but
I will bump semver major just in case.

Also, cleaned up a bunch of lets to consts and added a tslint config.

1.2.0: Sharing is caring

Add a simple replay to the main model share to help with timing issues of teeth subscriptions.

1.1.1: JSPM familiar

Add explicit package metadata for JSPM.

1.1.0: ES5 and ES2015 build

Splits ES5 and ES2015 into separate builds.

1.0.0: First Post!

Published to npm and everything!
