/**
 * @class   vtkGlobFileNames
 * @brief   find files that match a wildcard pattern
 *
 * vtkGlobFileNames is a utility for finding files and directories
 * that match a given wildcard pattern.  Allowed wildcards are
 * *, ?, [...], [!...]. The "*" wildcard matches any substring,
 * the "?" matches any single character, the [...] matches any one of
 * the enclosed characters, e.g. [abc] will match one of a, b, or c,
 * while [0-9] will match any digit, and [!...] will match any single
 * character except for the ones within the brackets.  Special
 * treatment is given to "/" (or "\" on Windows) because these are
 * path separators.  These are never matched by a wildcard, they are
 * only matched with another file separator.
 * @warning
 * This function performs case-sensitive matches on UNIX and
 * case-insensitive matches on Windows.
 * @sa
 * vtkDirectory
