create initial highway balloon

[plastikfan]

The initial version does not have to be visually appealling. The glamification will be handled by another issue. This issue will focus on layout and behaviour only.

The highway will eventually consist of the following components:

• the lanes
• paginator

The paginator should be addressed in a separate issue.

For the purposes of a hosting test app, the highway should be wrapped in a view which in itself contains a prompt. This will be a test promot that will allow a lane to be added or removed on a last in first out basis (stack).
