/**
* This class defines the Certificate Policies Extension.
*
*
* The certificate policies extension conatins a sequence of policy information terms, each of which consists of an
* object identifier (OID) and optional qualifiers. These policy information terms indicate the policy under which the
* certificate has been issued and the purposes for which the certificate may be used. Aplications with specific policy
* requirements are expected to have a list of those policies which they will accept and to compare the policy OIDs in
* the certificate to that list. If this extension is critical, the path validation software must be able to interpret
* this extension, or must reject the certificate.
*
*
* CertificatePolicies ::= SEQUENECE OF PolicyInformation
