Add geonode

[samrocksc]

What's this PR do?

This PR cleaned up a little bit of code in the camera(sorry). I also added all of the necessary files to create a geonode that reports back the navigator.getCurrentLocation(); method of the browser. I will probably make more changes in the future if I find any compatibility issue; however, I did not find any at this point.

The data is attached to msg.location.

What are the important parts of the code?

Per future documentation here are the files required in order to create a node:

• /nodes/nodeName.html
• /nodes/nodeName.js
• /src/editor/nodeDefs/filename/nodeName.js
• /src/editor/nodeDefs/index.js
• /src/red/nodes/registry/cachedNodeFiles.js
• /src/red/nodes/registry/loader.js

  How should this be tested by the reviewer?

This can be tested by the standard build processes in package.json

Is any other information necessary to understand this?

not really

What are the relevant tickets? (Please add closes, refs, etc)
