Not able to use it

[radtech]

I imported the file app.js in code.
and tried passing

`var state = {
token: '',
debug: window.location.search.indexOf('debug')>-1,
mode: 'driving',
direction:'divergent',
threshold: 3600,
resolution: 1.5,
batchSize: 400,
inspector: false
};

isochrone([12.957194522,77.5682954863], state, function(output){
console.log(output);
})`

but I am getting an error
Uncaught TypeError: Cannot read property 'durations' of undefined
at Object. (app.js:157)
at Dispatch.call (app.js:2266)
at XMLHttpRequest.respond (app.js:2516)

my call is
https://api.mapbox.com/directions-matrix/v1/mapbox/driving/12.9572,77.5683;12.9572,77.5683;12.9572,77.5873;13.0454,77.5683;13.0454,77.5873?sources=0&destinations=all&access_token=

I've been getting this same error intermittently. (maybe 1 time out of 5) Did you ever resolve this issue?

@mikelinc this is likely because you're rate-limited -- non-enterprise plans are unfortunately capped at 60 Matrix requests per second

I just merged a PR that addresses/alleviates some of these relevant troubles #14
