Add readme file (#39)

* Add readme file

* Long overdue readme file for the client
* set httpRequestTimeout & httpPoolConnections while creating TransportConfig

  Currently NewTransportConfig takes an "httpRequestTimeout int" but it is not
  used to fill in the returned "cfg TransportConfig", which is wrong. Fixing the
  issue in this patch.

+       )
+
+       func main() {

+   		    Host:     "<NIOS grid IP>",
+   		    Version:  "<WAPI version>",
+   		    Port:     "PORT",
+   		    Username: "username",
+   		    Password: "password",
+   	    }

+   	    requestBuilder := &ibclient.WapiRequestBuilder{}
+   	    requestor := &ibclient.WapiHttpRequestor{}
+   	    conn, err := ibclient.NewConnector(hostConfig, transportConfig, requestBuilder, requestor)
+   	    if err != nil {
+   		    fmt.Println(err)
+   	    }
+   	    objMgr := ibclient.NewObjectManager(conn, "myclient", "")
+   	    //Fetches grid information
+   	    fmt.Println(objMgr.GetLicense())
+       }
