/*APPU NAIR PROGRAMMERS REPURPOSING NOTE THESE 05/03/2013
* THIS PROJCETS SERVICE REFERENCES ARE POINTING TO LIVELINK TEST SYSTEM SO IF YOU BUILD AND MAKE THIS WORK CHECK
* THE OBJECTS IN .
* YOU WILL NEED A MANUAL LOGIN AS THE wcf EXPOSED IS ANONYMOUS SCHEME.SSO DOES NOT WORK
* CONTENTSERVICE IS THE WAY YOU GET BIG FILES IN.IF YOU HAVE MORE THAN 2 GB UPLOADS YOU NEED
* SOME TWEAKS IN CLIENTS AS WELL AS THE WEB.CONFIG IN THE LIVLINK IIS SRVER
* if code works and you re-run the sample you will get "object exists" as livelink will allow only one object
* by that name.you can add a new version to the object as livelink is a DMS
* also if you do ListContainer call you can enumerate children and find it yourself
