/**

 * GTSAM Wrap Module Definition
 *
 * These are the current classes available through the matlab toolbox interface,
 * add more functions/classes as they are available.
 *
 * Requirements:
 *   Classes must start with an uppercase letter
 *      - Can wrap a typedef
 *   Only one Method/Constructor per line, though methods/constructors can extend across multiple lines
 *   Methods can return
 *     - Eigen types:       Matrix, Vector
 *     - C/C++ basic types: string, bool, size_t, int, double, char, unsigned char
 *     - void
 *     - Any class with which be copied with boost::make_shared()
 *     - boost::shared_ptr of any object type
 *   Constructors
 *     - Overloads are supported
 *     - A class with no constructors can be returned from other functions but not allocated directly in MATLAB
 *   Methods
 *     - Constness has no effect
 *     - Specify by-value (not reference) return types, even if C++ method returns reference
 *     - Must start with a letter (upper or lowercase)
 *     - Overloads are supported
 *   Static methods
 *     - Must start with a letter (upper or lowercase) and use the "static" keyword
 *     - The first letter will be made uppercase in the generated MATLAB interface
 *     - Overloads are supported
 *   Arguments to functions any of
 *      - Eigen types:       Matrix, Vector
 *      - Eigen types and classes as an optionally const reference
 *     - C/C++ basic types: string, bool, size_t, size_t, double, char, unsigned char
 *     - Any class with which be copied with boost::make_shared() (except Eigen)
 *     - boost::shared_ptr of any object type (except Eigen)
 *   Comments can use either C++ or C style, with multiple lines
 *   Namespace definitions
 *     - Names of namespaces must start with a lowercase letter
 *      - start a namespace with "namespace {"
 *      - end a namespace with exactly "}"
 *      - Namespaces can be nested
 *   Namespace usage
 *      - Namespaces can be specified for classes in arguments and return values
 *      - In each case, the namespace must be fully specified, e.g., "namespace1::namespace2::ClassName"
 *   Includes in C++ wrappers
 *     - All includes will be collected and added in a single file
 *     - All namespaces must have angle brackets: <path>
 *     - No default includes will be added
 *   Global/Namespace functions
 *     - Functions specified outside of a class are global
 *     - Can be overloaded with different arguments
 *     - Can have multiple functions of the same name in different namespaces
 *   Using classes defined in other modules
 *     - If you are using a class 'OtherClass' not wrapped in this definition file, add "class OtherClass;" to avoid a dependency error
 *   Virtual inheritance
 *     - Specify fully-qualified base classes, i.e. "virtual class Derived : ns::Base {" where "ns" is the namespace
 *     - Mark with 'virtual' keyword, e.g. "virtual class Base {", and also "virtual class Derived : ns::Base {"
 *     - Forward declarations must also be marked virtual, e.g. "virtual class ns::Base;" and
 *       also "virtual class ns::Derived;"
 *     - Pure virtual (abstract) classes should list no constructors in this interface file
 *     - Virtual classes must have a clone() function in C++ (though it does not have to be included
 *       in the MATLAB interface).  clone() will be called whenever an object copy is needed, instead
 *       of using the copy constructor (which is used for non-virtual objects).
 *     - Signature of clone function - will be called virtually, so must appear at least at the top of the inheritance tree
 *           virtual boost::shared_ptr<CLASS_NAME> clone() const;
 *   Class Templates
 *     - Basic templates are supported either with an explicit list of types to instantiate,
 *       e.g. template<T = {gtsam::Pose2, gtsam::Rot2, gtsam::Point3}> class Class1 { ... };
 *       or with typedefs, e.g.
 *       template<T, U> class Class2 { ... };
 *       typedef Class2<Type1, Type2> MyInstantiatedClass;
 *     - In the class definition, appearances of the template argument(s) will be replaced with their
 *       instantiated types, e.g. 'void setValue(const T& value);'.
 *     - To refer to the instantiation of the template class itself, use 'This', i.e. 'static This Create();'
 *     - To create new instantiations in other modules, you must copy-and-paste the whole class definition
 *       into the new module, but use only your new instantiation types.
 *     - When forward-declaring template instantiations, use the generated/typedefed name, e.g.
 *       class gtsam::Class1Pose2;
 *       class gtsam::MyInstantiatedClass;
 *   Boost.serialization within Matlab:
 *     - you need to mark classes as being serializable in the markup file (see this file for an example).
 *     - There are two options currently, depending on the class.  To "mark" a class as serializable,
 *       add a function with a particular signature so that wrap will catch it.
 *        - Add "void serialize()" to a class to create serialization functions for a class.
 *          Adding this flag subsumes the serializable() flag below. Requirements:
 *             - A default constructor must be publicly accessible
 *             - Must not be an abstract base class
 *             - The class must have an actual boost.serialization serialize() function.
 *        - Add "void serializable()" to a class if you only want the class to be serialized as a
 *          part of a container (such as noisemodel). This version does not require a publicly
 *          accessible default constructor.
 *   Forward declarations and class definitions for Cython:
 *     - Need to specify the base class (both this forward class and base class are declared in an external cython header)
 *       This is so Cython can generate proper inheritance.
 *       Example when wrapping a gtsam-based project:
 *          // forward declarations
 *          virtual class gtsam::NonlinearFactor
 *          virtual class gtsam::NoiseModelFactor : gtsam::NonlinearFactor
 *          // class definition
 *          #include <MyFactor.h>
 *          virtual class MyFactor : gtsam::NoiseModelFactor {...};
 *    - *DO NOT* re-define overriden function already declared in the external (forward-declared) base class
 *        - This will cause an ambiguity problem in Cython pxd header file
