is.null.cxxfun

The function object returned by <code>cxxfunction</code> cannot be 
 saved across R sessions. This function can be used to see
 if we still have a valid function object. Also this function 
 can be used for functions returned by <code>grab.cxxfun</code>
 of S4 class <code>cxxdso</code> since these functions are essentially
 created by <code>cxxfunction</code> or similarly.

Extend 'cxxfunction' by saving the dynamic shared objects
for reusing across R sessions.
