	 This class provides a contact database scheme. <br>
	 It attempts to be based on the vcard 2.1 standard, with mods as needed to make for more reasonable sql storage. <br>
	 The LDAP schema used here may require installation of schema files available in the phpgwapi/doc/ldap dir.
	 Please see the README file there.
	 Syntax: CreateObject('phpgwapi.contacts'); <br>
	 Example1: $contacts = CreateObject('phpgwapi.contacts');
