 * ColourMap is our table which maps the unsigned integer keys stored in

00042 class ColourMap
    // Functions:

     * Initialises an ColourMap with a default element set to
     * whatever COLOUR_DEF_X defines the colour to be (see the source file)
     * Initialises an ColourMap with a default element set to
     * the value of the Colour passed in.
    ColourMap(const Colour& input);

     * Returns the Colour associated with the item_num passed in.  Note that
     * if the item_num doesn't represent a valid item, the routine returns
     * the value of the Default colour.  This means that if somehow some of
     * the Segments get out of sync with the ColourMap and have invalid
     * colour values, they'll be set to the Composition default colour.
    Colour getColourByIndex(unsigned int item_num) const;

     * Returns the string associated with the item_num passed in.  If the
     * item_num doesn't exist, it'll return "" (the same name as the default
     * colour has - for internationalization reasons).
    std::string getNameByIndex(unsigned int item_num) const;

     * If item_num exists, this routine deletes it from the map.
    bool deleteItemByIndex(unsigned int item_num);

     * This routine adds a Colour using the lowest possible index.
    bool addItem(Colour colour, std::string name);

     * This routine adds a Colour using the given id.  ONLY FOR USE IN
     * rosexmlhandler.cpp
    bool addItem(Colour colour, std::string name, unsigned int id);

     * If the item with item_num exists and isn't the default, this
     * routine modifies the string associated with it
    bool modifyNameByIndex(unsigned int item_num, std::string name);

     * If the item with item_num exists, this routine modifies the 
     * Colour associated with it
    bool modifyColourByIndex(unsigned int item_num, Colour colour);

     * If both items exist, swap them.  
    bool swapItems(unsigned int item_1, unsigned int item_2);

//    void replace(ColourMap &input);

     * This returns a const iterator pointing to m_map.begin()
    RCMap::const_iterator begin();

     * This returns a const iterator pointing to m_map.end()
    RCMap::const_iterator end();
