## Detailed Description

This is a first attempt at a message handler.

The COIN Project is in favo(u)r of multi-language support. This implementation of a message handler tries to make it as lightweight as possible in the sense that only a subset of messages need to be defined --- the rest default to US English.

The default handler at present just prints to stdout or to a FILE pointer

Todo:
  This needs to be worked over for correct operation with ISO character codes.

## Enumeration Type Documentation

enum CoinMessageMarker

Enumerator:

  CoinMessageEol |
  CoinMessageNewline |

## Function Documentation

bool CoinMessageHandlerUnitTest | ( |  | ) |

A function that tests the methods in the CoinMessageHandler class.

The only reason for it not to be a member method is that this way it doesn't have to be compiled into the library. And that's a gain, because the library should be compiled with optimization on, but this method should be compiled with debugging.
