RealBasic class development - repost

I need a class written in Relabasic with RealStudio 2012. With this class I must be able to parse a vCard (.vcf file) containing one or more contacts (including the photo tag). I want support for v2.1/3.0/4.0 vcard versions (selectables). I need methods to easily dispaly the vcard information into a listbox(hierarchical). I must be able to create a vCard contact in order to export the .vcf file. No encrypted class or modules (full source code).
