Create HTTPCasClient

Create a RESTful secured API using CAS,

Make sure You have a working CAS setup at "https://XX.4.YY.63:8443/cas/";
I used JDBC based Authentication here, https://wiki.jasig.org/display/CASUM/Using+JDBC+for+Authentication

Notes:
1. Configure: https://wiki.jasig.org/display/CASUM/RESTful+API
2. Test : Using commons http client
3. Workflow,
	>Get the TicketGrantingTicket from server = "https://XX.4.YY.63:8443/cas/v1/tickets";
	>Get the ServiceTicket service = "https://XX.4.YY.77:8443/XXYYWeb/secure";
	>Based on the service ticket GET access to the REST API service. This service can be exposed as in the below sample
