class PKCS15

This class provides for direct access to a PKCS#15 data structure on a card.

The calling application will typically use:

 var card = new Card(_scsh3.reader);
 var p15 = new PKCS15(card);
 var appllist = p15.readApplicationDirectory();
 var aid;
 for (var i in appllist) {
   print(i);
   aid = i;
 }
 var at = appllist[aid];
 p15.readObjectListForApplication(at);
 for (var i = 0; i < at.objlist.length; i++) {
   print(at.objlist[i]);
 }
