New Interactive Services (NIS)

New Interactive Services provides the API similar to the traditional AIS but with some important differences/improvements:

This package is an experimental one, it does not yet provide the support of many features that you can find in AIS, e.g., visualization of topology, local contexts. It can be used to create efficient OpenGl-base visualization components, however, it does not replace AIS. You can think of NIS as a complement to the traditional AIS, better suited to some special tasks, rather than its replacement.
