commit 194ebf81f025c450555ec8cf3a98653bb1307c4c
Author: Steven Peters <scpeters@osrfoundation.org>

    Fix gazebo7 build errors
    
    The SensorPtr types have changed from boost:: pointers
    to std:: pointers,
    which requires boost::dynamic_pointer_cast to change to
    std::dynamic_pointer_cast.
    A helper macro is added that adds a `using` statement
    corresponding to the correct type of dynamic_pointer_cast.
    This macro should be narrowly scoped to protect
    other code.
