[Name] FILENAME

[Description] This creates a text box where the user may enter in a filename and
              path. If the button is pressed, a file picker dialog appears and
              the user is able to pick certain files based on the filename
              filter (use asterisks (*) as a wildcard (e.g. *.txt).

              The filters are made in pairs, with a filter
              description(<filterDes>) and the actual filter. Spaces are not
              allowed in the description. Multiple extensions may be separated
              by a semicolon.

              Note: When the macro name starts with SourceDataset (case
              insensitive), the type it will be translated into a MULTIFILE
              type. This is to maintain reverse compatibility from before the
              MULTIFILE type even existed (see Example).
