//
// Synopsis:    Present the user with a file browser window to select a file for
//              open or save.
//
// Parameters:  filePath         - a reference parameter to receive the full
//                                 file path from the dialog.  If not NULL on
//                                 input, the initial value is used as the
//                                 starting location for the dialog.
//              filePathSize     - the maximum length of the filePath buffer.
//              dialogTitle      - the caption to appear in the dialog title
//                                 bar.
//              extensionFilter  - A filter specifiying the types of files that
//                                 are eligilble for selection.  It must end
//                                 in "||" with all entries separated by "|".
//                                 Generally entries will be in pairs; the 
//                                 first is a type description and the second
//                                 is the actual filter.  e.g./
//                                 "Raddle Data(*.rdl)|*.rdl|All Files(*.*)|*.*||".
//              defaultExtension - if not NULL, then the given extension will 
//                                 automatically appended to an extensionless
//                                 entry in the Filename box.
//              broserType       - OPEN | SAVE.  Default is OPEN.
//
// Returns:     true, if a filePath is set; false if the dialog is cancelled.
//
// Notes:  The filePath will have "/" slashes and not "\" slashes on return.
