STL containers with non-assignable types break the build

[dbankieris]

ICG should not create checkpoint restore code for any STL container whose type hides operator=. Note that a container of pointers to such a type is ok, but not a container of actual instances of such a type.

class Foo {
    private:
    void operator=(const Foo&);
};

#include "sim_objects/default_trick_sys.sm"

##include <vector>
##include "Foo.hh"

class Sandbox : public Trick::SimObject {

    const std::vector<Foo> foos;

};
