Validates a given URL.

RetVal = object.IsURL(URL)
The object or objects this method applies to.
The URL to validate.
TRUE: The string represents a valid URL.
FALSE: The string is not a valid URL.
The definition of a "valid" URL is application-dependent, in that a given third-party application may not be interested in supporting all Internet protocols. For instance, an application that attempts to connect users to websites would probably not need to provide access to FTP sites. In this hypothetical application, a FALSE value would be returned if a URL that begins with something other than "http://" was entered.
The default functionality of this method for AutoCAD supports FTP, HTTP, HTTPS, and FILE protocols.
