the components defined in an XML document and (if possible) their Doc strings.  Usage:
    python XmlInfo.py [fileName] [-b] [-i]
    Example:
    python XmlInfo.py config/C5Sign.xml

With no flags all components are printed.  With -b, behaviors are printed.  With -i, inputs are
printed.  (And both if both are specified)
