/**
* A function that prepares the Cycle application to be executed. Takes a `main`
* function and prepares to circularly connects it to the given collection of
* driver functions. As an output, `setup()` returns an object with three
* properties: `sources`, `sinks` and `run`. Only when `run()` is called will
* the application actually execute. Refer to the documentation of `run()` for
* more details.
*
* **Example:**
* ```js
* import {setup} from '@cycle/run';
* const {sources, sinks, run} = setup(main, drivers);
* // ...
* const dispose = run(); // Executes the application
* // ...
* dispose();
* ```
*
* @param {Function} main a function that takes `sources` as input and outputs
* `sinks`.
* @param {Object} drivers an object where keys are driver names and values
* are driver functions.
* @return {Object} an object with three properties: `sources`, `sinks` and
* `run`. `sources` is the collection of driver sources, `sinks` is the
* collection of driver sinks, these can be used for debugging or testing. `run`
* is the function that once called will execute the application.

/**
* A partially-applied variant of setup() which accepts only the drivers, and
* allows many `main` functions to execute and reuse this same set of drivers.
*
* Takes an object with driver functions as input, and outputs an object which
* contains the generated sources (from those drivers) and a `run` function
* (which in turn expects sinks as argument). This `run` function can be called
* multiple times with different arguments, and it will reuse the drivers that
* were passed to `setupReusable`.
*
* **Example:**
* ```js
* import {setupReusable} from '@cycle/run';
* const {sources, run, dispose} = setupReusable(drivers);
* // ...
* const sinks = main(sources);
* const disposeRun = run(sinks);
* // ...
* disposeRun();
* // ...
* dispose(); // ends the reusability of drivers
* ```
*
* @param {Object} drivers an object where keys are driver names and values
* are driver functions.
* @return {Object} an object with three properties: `sources`, `run` and
* `dispose`. `sources` is the collection of driver sources, `run` is the
* function that once called with 'sinks' as argument, will execute the
* application, tying together sources with sinks. `dispose` terminates the
* reusable resources used by the drivers. Note also that `run` returns a
* dispose function which terminates resources that are specific (not reusable)
* to that run.
* @function setupReusable

* The `main` function expects a collection of "source" streams (returned from
* drivers) as input, and should return a collection of "sink" streams (to be
* given to drivers). A "collection of streams" is a JavaScript object where
* keys match the driver names registered by the `drivers` object, and values
* are the streams. Refer to the documentation of each driver to see more
* details on what types of sources it outputs and sinks it receives.
