Delete stored madrat messages from the madrat environment. The madrat environment
behaves similar like global options, except that 1) messages will also
be stored in cache files and restored when a cache file is being loaded and
2) messages are always stored in lists with messages split by function calls
where the message was triggered.
Usage
resetMadratMessages(name = NULL, fname = NULL)
Arguments
name
The category for which the messages should be reset (if not set
messages in all categories will be reset)
fname
function name for which the entries should be reset (if not specified
messages for all function names will be reset)
