    \brief
        Editbox class for the FalagardBase module.

        This class requires LookNFeel to be assigned.  The LookNFeel should provide the following:

        States:
            - Enabled    - Rendering for when the editbox is in enabled and is in read-write mode.
            - ReadOnly  - Rendering for when the editbox is in enabled and is in read-only mode.
            - Disabled  - Rendering for when the editbox is disabled.
            - ActiveSelection   - additional state rendered for text selection (the imagery in this section is rendered within the selection area.)
            - InactiveSelection - additional state rendered for text selection (the imagery in this section is rendered within the selection area.)

        NamedAreas:
            TextArea    - area where text, selection, and carat imagery will appear.

        PropertyDefinitions (optional, defaults will be black):
            - NormalTextColour   - property that accesses a colour value to be used to render normal unselected text.
            - SelectedTextColour - property that accesses a colour value to be used to render selected text.

        Imagery Sections:
            - Carat
