Trying to run this, I get "Request has failed. Status Code: 404"

Is this because the data is only in the specs?

Yeah, that will be fixed.

The description shouldn't just repeat the name.

Totally just semantics but technically, though it uses .pnts files, this isn't really 3D Tiles, is it?

I was debating this too. I'll move it out of 3D Tiles.

Change Log
==========

### 1.48 2018-08-01
### 1.48 - 2018-08-01

##### Additions :tada:
* Added support for loading Draco compressed Point Cloud tiles for 2-3x better compression. [#6559](https://github.com/AnalyticalGraphicsInc/cesium/pull/6559)
* Added `TimeDynamicPointCloud` for playback of time-dynamic point cloud data, where each frame is a 3D Tiles Point Cloud tile. [#6721](https://github.com/AnalyticalGraphicsInc/cesium/pull/6721)

### 1.47 - 2018-07-02
