The version of the ProgressBar in WVUI has only the indeterminate state: as a first step for this component, let's recreate the WVUI version in Codex.
Acceptance criteria (or Done)
- ProgressBar component added to Codex (code and demo)
- ProgressBar component shows the indeterminate state
- Component height should be 16px (now it's 18px). Outline should be inside instead outside to avoid to increase the component height.
