(Swift 2) Load Certs from Java KeyStore into Trusted CA Roots

Demonstrates how to load a Java KeyStore containing CA root certificates that are to be trusted by the application. This can be done once at the beginning of an application, and then the trusted roots can be activated so that only these root CA certs are trusted by the application for any TLS connections.
