bioformats2xml

  BIOFORMATS2XML - return XML metadata (and write an XML file) using Bio-Formats

  [X, XMLFILENAME] = BIOFORMATS2XML(FILENAME, XMLFILENAME)

  Uses Bio-Formats to read XML metadata from the file FILENAME.
  If XMLFILENAME is not specified, a temporary file is created for that purpose.
  The XML character is returned in X. 
  The XMLFILENAME used is returned in XMLFILENAME.

  This function fixes an error in Bio-Formats (the XML file is in
  iso-88509-1, not UTF-8 as Bio-Formats outputs).
