Update icons for the Outline and Quick Outline
Extracted from #40 See https://github.com/RepreZen/SwagEdit/pull/178#issuecomment-239298500 and https://github.com/RepreZen/SwagEdit/pull/178#issuecomment-239302105 for details
The icons are provided in the attached archive outline_icons.zip
I started to change the icons. The icons you provided are quite specific and are not easy to map to swagger concepts. It would help if we modify the way we get type information from nodes inside the document. We get those types information from the swagger schema, but those are difficult to interpret for now.
Here a screenshot of what I got for now.

The list of icons that are currently mapped into swagger elements
| icon name | swagger element |
|---|---|
| resource | pathItem |
| response | responses |
| response_* | responseValue |
| requestParameter | parametersList |
| referenceLink | $ref |
| dataType | schema |
| method | operation (get, post, ...) |
List of icons that are not mapped into swagger
| icon name |
|---|
| collectionResource |
| objectResource |
| headerParameter |
| message |
| package_obj |
| referenceEmbed |
| request |
| resourceRepresentation |
This leaves us with also quite a few elements in swagger that have no icons (not exhaustive list)
| swagger element |
|---|
| info |
| schemes |
| tags |
| paths |
| consumes |
| produces |
| definitions |
| properties |
Thanks @ghillairet . I think it's going to take a little time for us to digest this and come up with a more complete set of icons. So I suggest putting this workstream aside for a while, until we can give you some more guidance.
