+This function will start a new session and clear any existing session information.  This generates a random session ID and passes it as a cookie back to the browser, so it needs to be called before any other data is sent out.  You can then set session variables through the global ''$_SESSION'' array.
+This is only applicable for HTTP initiated scripts.  The ''$_SESSION'' array is available to all HTTP scripts to allow for persistent variables to be shared between scripts.  This array is associated with the script based on the cookie created.
+====Parameters====
