var Rx = require('rx');

/**
 * Generate a 'sliding window' of the input time series. Please note that this function assumes that the observable
 * input series is a linear time series, that is: `selector(n) < selector(n+1)`. Otherwise things will get weird.
 * 
 * @param windowSizeMs - size of the sliding window in ms
 * @param {function} [selector] - selector function that obtains the unix timestamp value for a given item
 * @param {Rx.Scheduler} [scheduler] - optional scheduler
 * @returns {Rx.Observable<T>}
