Cadence detection for event-driven accelerometer data

Usage

``js
var QuickCadence = require('quickcadence')

// On a Node streams2 stream, or BaconJS Observable stream.
// Returns a BaconJS Observable.
//
// The stream must be object that matches the schema:
// {x: , y: , z: }
var cadenceStream = QuickCadence.pipe(stream);
cadenceStream.onValue(function(val) { console.log(val) });

// Values emitted are integers of the current cadence calculation.
// 93.22
// 88.11
// 79.25 ...
`

Limitations

Power is matched off of the y acceleration axis, which works well for
wrist-mounted accelerometers (watches). Further work can be done to
generalize this algorithm to all-axes calculations.

Data harness for your accelerometer data

Put CSV dump of files with other csv files in the samples directory.

Start the dev server to load the data harness:

$ npm start
$ open http://localhost:8080/reference/index.html

Build

$ npm run build

Assets are generated into the builds/` directory.
