Fixed size function

===================

Fixed size function wrapper like [std::function](http://en.cppreference.com/w/cpp/utility/functional/function) to avoid dynamic memory allocation.

Usage:

```c++

#include "fixed_size_function.hpp"

int f(int a)

{

	std::cout << __FUNCTION__ << "\n";

	return a; 

}

int g(int a, int b)

{

	std::cout << __FUNCTION__ << "\n";

	return a;

}

struct X

{

	int operator()(int a) const

	{

		std::cout << __FUNCTION__ << "\n";

		return a;

	}

	int mem_fun(int a)

	{

		std::cout << __FUNCTION__ << "\n";

		return a;

	}

};

int main()

{

	fixed_size_function fun;

	// Functor

	X x;

	fun = x;

	fun(1);

	// Free function

	fun = f;

	fun(2);

	// Bind function

	fun = std::bind(g, std::placeholders::_1, 0);

	fun(3);

	// Bind member function

	fun = std::bind(&X::mem_fun, x, std::placeholders::_1);

	fun(4);

	// Lambda

	fun = [](int a) -> int

	{

		std::cout << __FUNCTION__ << "\n";

		return a;

	};

	fun(5);

}

```
