/**
    @class wxExtHelpController

    This class implements help via an external browser.
    It requires the name of a directory containing the documentation
    and a file mapping numerical Section numbers to relative URLS.

    The map file contains two or three fields per line:
    numeric_id  relative_URL  [; comment/documentation]

    The numeric_id is the id used to look up the entry in
    DisplaySection()/DisplayBlock(). The relative_URL is a filename of
    an html file, relative to the help directory. The optional
    comment/documentation field (after a ';') is used for keyword
    searches, so some meaningful text here does not hurt.
    If the documentation itself contains a ';', only the part before
    that will be displayed in the listbox, but all of it used for search.

    Lines starting with ';' will be ignored.
