1) updated original rt0 to remove libstrongswan dependency
a) identity credential being made/accessed with openssl api calls
(X509/EVP_PKEY pem)
b) attribute credential being made/access via xmlsec1 (custom XML
structure)
2) refactored libcreddy into libabac and now one ABAC namespace for
libabac
3) added attribute_rule suboption to creddy's attribute as another way
to insert access rule
4) added some regression tests into example directory
5) updated some docs.
