Solved: Finally found how to set the global log level for the 
entire app...

   import std.experimental.logger;
   globalLogLevel(LogLevel.warning);

Could a list of the module-level functions be provided in the 
documentation page for std.experimental.logger ?  Other modules 
such as std.file have this but it appears to be lacking for this 
one.
