/*
 *HOWTO:
 *
 * Simply #include the header file "StatusBox.hpp" in any source code
 * you want use it from. Three MACROS are defined for simple messages:

 STATUS("This is the message");
 STATUS(somestring);
 WARNING("A warning");
 ERROR("An Error");

 * These macros accept a single character string argument. The only
 * differences are the color fo the text output to the list. If you
 * would like to send more detailed information with formatting you
 * must call status(char *format, ...) directly as follows:

 StatusBox::Instance()->status(
 "I want to print out the following %d %f", anInteger, aFloat);

 or use warning(char *format, ...), or error(char *format, ...);

 * StatusBox is implemented as a singleton, which means the constructor
 * is protected and there is a single static instance. You can only
 * get to the object using the Instance() method, which returns a
 * pointer to the static object. This means all status messages go the
 * same place. This a convenient substitute for a terminal window */
