properly correct the CSS to show the red number per tooltip: now the red circle is bigger and fits each number easily.
feature: provide role-specific intro texts: site visitors may have different roles and require different assistance and thus feature makes this possible, including switching roles 'live' in-app.

Two examples are included which showcase the augmented behaviour.
- documented the goToStep() API a bit more, mentioning that the step number is '1 based'

- introduced the getCurrentStep() API so user code can store the current IntroJS state when the overlay is clicked or the introduction is aborted another way, to be continued at a later time.

- bumped version to 0.6.1
initial prepwork phase 1 for preconditioning and tracking introduction state.
