/**
*
* Minimum value is determined incrementally with arrival of each value from the data stream.
*
* The [`compute()`](https://winkjs.org/wink-statistics/Stream.html#compute) requires
* a single numeric value as argument.
*
* The [`result()`](https://winkjs.org/wink-statistics/Stream.html#result) returns
* an object containing `min`.
*
* @memberof streaming#
* @return {Stream} Object containing methods such as `compute()`, `result()` & `reset()`.
* @example
* var minimum = min();
* minimum.compute( 3 );
* minimum.compute( 6 );
* minimum.value();
* // returns 3
* minimum.result();
* // returns { min: 3 }
