Detailed Description
template<typename float_type>
class c2_const_ptr< float_type >
create a container for a c2_function which handles the reference counting.
It is useful as a smart container to hold a c2_function and keep the reference count correct. The recommended way for a class to store a c2_function which is handed in from the outside is for it to have a c2_ptr member into which the passed-in function is stored. This way, when the class instance is deleted, it will automatically dereference any function which it was handed.
This class contains a copy constructor and operator=, to make it fairly easy to make a std::vector of these objects, and have it work as expected.

convenience operator to make us look like a function
- Parameters
-
x the value at which to evaluate the contained function
- Returns
- the evaluated function
- Note
- If you using this repeatedly, do const c2_function<float_type> &func=ptr; and use func(x). Calling this operator wastes some time, since it checks the validity of the pointer every time.

release the function without destroying it, so it can be returned from a function
This is usually the very last line of a function before the return statement, so that any exceptions that happen during execution of the function will cause proper cleanup. Once the function has been released from its container this way, it is an orhpaned object until the caller claims it, so it could get lost if an exception happens.
