Detailed Description

Handles warning messages in a standardized fashion.

Warning messages can be annoying when they are repeated too many times. This class provides a standard means of handling warning messages. The user can select to:

• issue a warning only once (the first time it occurs);
• print a summary of the number of times the warning was issued; and/or
• issue the warning every time
