Pause a stream's data events
$ npm install pausevar pause = require('pause')Pause the data events on a stream and return a handle to resume or end the stream.
Dispose of the handle. This does not end the stream, but it simply discards
the event collection, making handle.resume() a no-op.
Resume the stream by re-emitting all the data events in the same order,
followed by an end event, if that was emitting during the pause.
