[Live-devel] Error reporting guidelines

Best is to use "env <<", because that will work even if you later 
change your "UsageEnvironment" to use something other than console 
'stderr'.  ("fprintf(stderr, ...)" is still used in a few places in 
the code for casual debugging, but shouldn't really be; "env <<" is 
the preferred way to output error messages.

(In contrast, "env.setResultMsg()" is used to assign a (usually 
error) message that you may or may not necessarily want to print out 
later.)
