Constuctor flags

• desc_2_md : The description property is not a summary, and hence should be put in as a metadata pair. The label generated will be "Description". The default is true.
• related_2_md : The related property is not a homepage, and hence should be put in as a metadata pair. The label generated will be "Related". The default is false (and hence the property will simply be renamed as homepage)
• ext_ok : Should extensions be copied through to the new version. The default is false.
• default_lang : The default language to use for language maps. The default is "@none".
• deref_links : Should links without a format property be dereferenced and the HTTP response inspected for the media type? The default is true.
• debug : Are we in debug mode and should spit out more warnings than normal? The default is false
