loadJson(url, headers) → Promise
Asynchronously loads the given URL as JSON. Returns a promise that will resolve to
a JSON object once loaded, or reject if the URL failed to load. The data is loaded
using XMLHttpRequest, which means that in order to make requests to another origin,
the server must have Cross-Origin Resource Sharing (CORS) headers enabled. This function
adds 'Accept: application/json,*/*;q=0.01' to the request headers, if not
already specified.
