General utility class for various runtime diagnostics.

## Fields

- [HideSensitiveInformationFromLog](https://developer.rhino3d.com/api/gh2/type/grasshopper2.diagnostics.logger/hidesensitiveinformationfromlog.md): (static) Gets or sets whether personal information (such as UserName or MachineName ought to be included in the log. This flag must be set SUUUPER early on because the first thing the Logger does it dump a bunch of system info into the current log stream. At present, this value is not assigned at all, given that https://www.mcneel.com/privacy allows us to write all this data. The problem arises only when the user decides to share the log files, at which point it will be much harder to remove any specific entry.
