Help Changes

Environment reference material is grouped together to making it easier to find. We also added a Clones topic, providing information on preference settings and visual indicators, as well as creating, selecting, and unsharing clones. Supported File Formats is now part of Getting Started and provides the CAD versions supported for different VRED releases. We added workflows for Variant Sets Batch Rendering. And lastly, thank you for your feeback and comments! We are continually updating topics to address reported issues.
