* Note that all of these functions have two versions, a boost.function version and a
* standard C++ function pointer version. This allows reformulating the arguments of
* a function to fit the correct structure, which is useful for situations like
* member functions and functions with arguments not involved in the derivative:
*
* Usage of the boost bind version to rearrange arguments:
* for a function with one relevant param and an optional derivative:
* Foo bar(const Obj& a, boost::optional<Matrix&> H1)
* Use boost.bind to restructure:
* boost::bind(bar, _1, boost::none)
* This syntax will fix the optional argument to boost::none, while using the first argument provided
*
* For member functions, such as below, with an instantiated copy instanceOfSomeClass
* Foo SomeClass::bar(const Obj& a)
* Use boost bind as follows to create a function pointer that uses the member function:
* boost::bind(&SomeClass::bar, ref(instanceOfSomeClass), _1)
*
* For additional details, see the documentation:
* http://www.boost.org/doc/libs/release/libs/bind/bind.html
