Description

Provides ported functions/classes from gsl/pointers.

Adapted from the Guidelines Support Library v2.0.0. at https://github.com/Microsoft/GSL

Todo:

Replace comments referring to c++14-constexpr with constexpr when we require C++14.

Classes
class	gmx::compat::not_null< T >
	Restricts a pointer or smart pointer to only hold non-null values. More...

Macros
#define	Expects(cond)   GMX_ASSERT((cond), "Precondition violation")
	Contract-assurance macros that work like a simple version of the GSL ones.
#define	Ensures(cond)   GMX_ASSERT((cond), "Postcondition violation")

Functions
template<class T >
not_null< T >	gmx::compat::make_not_null (T &&t)
	Convenience function for making not_null pointers.
template<class T , class U >
auto	gmx::compat::operator== (const not_null< T > &lhs, const not_null< U > &rhs) -> decltype(lhs.get()==rhs.get())
	Operators to compare not_null pointers.
