export.OnError (ErrorMsg)

Parameters:
  ErrorMsg: any type, usually a string

Returns:
  nothing

Description:
  This is a user-defined hook into LuaFAR.
  If this function is defined by a user application, then, instead of displaying
  an error message box, LuaFAR calls this function, passing it the error message value.
  The return values of export.OnError (if any) are ignored.
