Update FrancesPerkins.xml with itemInContext info
Add ModsMetadata directory
Initial commit of Frances Perkins MODS metadata
Change how xlmns, xlink, xsi, and schemaLocation attributes are generated

Changed the way the above attributes, which are used in <modsCollection> or <mods>,
are generated by the xslt. The xlink and xsi namespace are now defined inside the
<stylesheet> tag, and the default namespace and the xsi:schemaLocation attribute are
set using <xsl:attribute> inside the <modsCollection> attribute.
Commit latest version of FrancesPerkinsMods.xml

Since changes the xslt filter used to generate the MODS
(changed how the attributes for <modsCollection> were generated),
the FrancesPerkinsMods.xml file had to be regenerated.
