New features

Multiple file display. Multiple files of the same type and coordinate reference system can be displayed together. A list of file names are given with the methods CV.UI.loadCaves( [array] ) or CV.Viewer.loadCaves( [array] ) and can also be loaded with 'drag and drop'.
Models can be annotated with dye traces. Annotations are stored in the user's browser session storage, and can be saved as JSON files for sharing on a web server alongside the model file. Annotations are added in the 'Edit' tab.
CaveView now exposes warning messages where Survex .3d models contain LRUD walls which extend beyond the end of a passage. This appears to be a common problem where sequences of cross sections are not terminated correctly. The stations where this problem has been detected are shown by selecting 'warnings' in the 'Settings' tab. These wall sections are automatically terminated at these points. (experimental).
