The fma_forest, fma_root_node and func_fma_steering classes lack a copy constructor.

The fma_forest, fma_root_node and func_fma_steering classes lack a
copy constructor.  However, they contain pointers to allocated memory
so this omission can be regarded as poor style.  We don't need to copy
such objects, so declare the copy constructor private to inhibit
accidental copying.
