/**
    @class wxStyledTextCtrl

    A wxWidgets implementation of the Scintilla source code editing component.

    As well as features found in standard text editing components, Scintilla
    includes
    features especially useful when editing and debugging source code. These
    include
    support for syntax styling, error indicators, code completion and call tips.
    The
    selection margin can contain markers like those used in debuggers to indicate
    breakpoints and the current line. Styling choices are more open than with many
    editors, allowing the use of proportional fonts, bold and italics, multiple
    foreground and background colours and multiple fonts.

    wxStyledTextCtrl is a 1 to 1 mapping of "raw" scintilla interface, whose
    documentation
    can be found in the Scintilla website.
