/**
* Takes an Observable of Observables, and collects all observables from it. Once the outer observable
* completes, it subscribes to all collected observables and "combines" their values, such that:
* - every time an observable emits, the returned observable emits
* - when the returned observable emits, it emits all of the most recent values by:
* - if a `project` function is provided, it is called with each recent value from each observable in whatever order they arrived,
* and the result of the `project` function is what is emitted by the returned observable
* - if there is no `project` function, an array of all of the most recent values is emitted by the returned observable.
* @param {function} [project] an optional function to map the most recent values from each observable into a new result. Takes each of the
* most recent values from each collected observable as arguments, in order.
* @returns {Observable} an observable of projected results or arrays of recent values.
