Subject: Moved rfrTriggerAction and rfrTriggerSaysGo from main/rfrInterface to
 here because I need to get at the pointer to the data structure with the
 information about the IO methods ... is there a better way to do this?

Added a new registerable function for each IO function

TimeToOutput(GH, int variable)

which returns true if it time to output a variable
