All classes from classes folder ported except - phpmailer(not required anymore), pchart(will be used as it is now, no need for any change), inputfilter(not required) . In dTexts class, all its functions dFunctions have been ported as a helper not as a library(which ideally they should be, but not working when we port them as library), datetimeconverter class require adodb-time.inc.php (date time library) so wrapped this file as well. Made some models that were required and a view.
