I have update slidingjoint and added visualization to both the examples. each file contains entire code to generate visualization.

Yes, I am using them are unit tests. Please refer to my PR #255

This issue must be fixed in #183.

I am currently working on fixing issues with camera including this one.

Okay, So I spent about one and a half day figuring out the reason and i still don't know. `camera.applyMatrix()` must work as it sets the value of `position`, `quaternions`...

Instead of an issue, I have asked on stackoverflow: http://stackoverflow.com/questions/30818179/rotation-does-not-change-after-setting-transformation-matrix-for-camera

@tarzzz but if we do `camera.matrixAutoUpdate = false` it works, thus, I don't think that its on the Python side. Something is overriding our matrix and I don't know what.

Okay, I am raising a PR for the same.

After #239 is merged, I am going to remove this from the milestone.

Yes, We have already removed loading simulation files and probably we should remove showing json files too.
