More native code gen functionality. 

Allow tables to be mapped to native types directly.  For example, a table
representing a vector3 (eg. table Vec3 { x:float; y:float; z:float; }) can
be mapped to a "mathfu::vec3" native type in NativeTables.  This requires
users to provide Pack and UnPack functions that convert between the
Table and native types.  This is done by adding the "native_type" attribute
to the table definition.

To support user-defined flatbuffers::Pack and flatbuffers::UnPack functions,
support a "native_include" markup that will generate a corresponding

Also add an UnPackTo function which allows users to pass in a pointer to
a NativeTable object into which to UnPack the Table.  The existing UnPack
function is now simply:

  NativeTable* UnPack() {
    NativeTable* obj = new NativeTable();
    Table::UnPackTo(obj);
    return obj;
  }

Finally, allow native types to be given a default value as well which are
set in the NativeTable constructor.  This is done by providing a
"native_default" attribute to the member of a table.

FlatBuffers is all about memory efficiency, which is why its base API is written
around using as little as possible of it. This does make the API clumsier

To use:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~{.cpp}
auto monsterobj = UnpackMonster(buffer);
// Autogenerated class from table Monster.
MonsterT monsterobj;
// Deserialize from buffer into object.
UnPackTo(&monsterobj, flatbuffer);
// Update object directly like a C++ class instance.
cout << monsterobj->name; // This is now a std::string!
monsterobj->name = "Bob"; // Change the name.
// Serialize into new flatbuffer.
FlatBufferBuilder fbb;
CreateMonster(fbb, monsterobj.get()); // Serialize into new buffer.
Pack(fbb, &monsterobj);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following attributes are specific to the object-based API code generation:
- `native_inline` (on a field): Because FlatBuffer tables and structs are
optionally present in a given buffer, they are best represented as pointers
(specifically std::unique_ptrs) in the native class since they can be null.
This attribute changes the member declaration to use the type directly
rather than wrapped in a unique_ptr.
- `native_default`: "value" (on a field): For members that are declared
"native_inline", the value specified with this attribute will be included
verbatim in the class constructor initializer list for this member.
- `native_type`' "type" (on a struct): In some cases, a more optimal C++ data
type exists for a given struct. For example, the following schema:
struct Vec2 {
x: float;
y: float;
}
generates the following Object-Based API class:
struct Vec2T : flatbuffers::NativeTable {
float x;
float y;
};
However, it can be useful to instead use a user-defined C++ type since it
can provide more functionality, eg.
struct vector2 {
float x = 0, y = 0;
vector2 operator+(vector2 rhs) const { ... }
vector2 operator-(vector2 rhs) const { ... }
float length() const { ... }
// etc.
};
The `native_type` attribute will replace the usage of the generated class
with the given type. So, continuing with the example, the generated
code would use |vector2| in place of |Vec2T| for all generated code.
However, becuase the native_type is unknown to flatbuffers, the user must
provide the following functions to aide in the serialization process:
namespace flatbuffers {
FlatbufferStruct Pack(const native_type& obj);
native_type UnPack(const FlatbufferStruct& obj);
}
Finally, the following top-level attribute
- native_include: "path" (at file level): Because the `native_type` attribute
can be used to introduce types that are unknown to flatbuffers, it may be
necessary to include "external" header files in the generated code. This
attribute can be used to directly add an #include directive to the top of
the generated code that includes the specified path directly.
# External references.
An additional feature of the object API is the ability to allow you to load
