/**
 * This library provides a HTML-template file based framework for Front End creating/editing/deleting records authenticated by email or fe_user login.
 * It is used in the extensions "direct_mail_subscription" and "feuser_admin" (and the depreciated(!) static template "plugin.feadmin.dmailsubscription" and "plugin.feadmin.fe_users" which are the old versions of these two extensions)
 * Further the extensions "t3consultancies" and "t3references" also uses this library but contrary to the "direct_mail_subscription" and "feuser_admin" extensions which relies on external HTML templates which must be adapted these two extensions delivers the HTML template code from inside.
 * Generally the fe_adminLib appears to be hard to use. Personally I feel turned off by all the template-file work involved and since it is very feature rich (and for that sake pretty stable!) there are lots of things that can go wrong - you feel. Therefore I like the concept used by "t3consultancies"/"t3references" since those extensions uses the library by supplying the HTML-template code automatically.
 * Suggestions for improvement and streamlining is welcome so this powerful class could be used more and effectively.
