44f1c9501b Add support for construction/assignment from two different integer types. 
Improve tests - check for mixed construction, and test domain_errors occur at the correct boundaries.

b2fc4f28e9 Comparators should be const member. 
And constexpr is no longer const after c++14: In c++11, non-static constexpr
member is implicitly const member, but after c++14 it isn't.

1307b89a2f Drop using directive, and fully qualify std names. 
Even with `using namespace std`, it's not safe to use names from std
without qualification in a header file, because the names may conflict
with names in the global namespace, leading to ambiguities.

bede51e319 We can have a throw expression in a converting constructor after all - fix so it works. 
Also test that converting constructor does throw when expected.

bf07b2f05d Use BOOST_THROW_EXCEPTION throughout. 
Note that template converting constructor is now no longer constexpr - however that was always really the case since a function that potentially throws can't be used in a constexpr context anyway.

5fddb3f889 Update rational.hpp 
Access to the numerator and denominator is unnecessarily inefficient when using rational with multiprecision types (ie where copying is relatively expensive), this change returns const-references to numerator and denominator.  In all other respects existing code should be uneffected by this change.
