Added num_get.cpp example using expected.
Added num_get example
Added operator->
Make use of normal include
More changes on NumGet example
Make the Jamfile work for me.
Delete binary files
Added NumGet returning pair<it,expected<int>>

Trere is a problem on the evaluation of noexcept(value(rhs))

//../../../boost/expected/expected.hpp:140:91: error: called object
type 'value_type' (aka 'long') is not a function or function pointer
//BOOST_CONSTEXPR expected(const value_type& rhs)
BOOST_NOEXCEPT_IF(BOOST_NOEXCEPT_EXPR(value(rhs)))
Added monad generic interface and make pair_expected a model of monad

The genric monad code should be moved to a monads.hpp file. I thinks
that this merits its own library.
Ignore all .o files
Fix some issues with monad operator |
Fix monad issue.

The probleme was because the result was always const
-> decltype(expr) const
Added operator|(pair_expected<T, I, E> m, F&& f)

No more need of the make_monad function
Rename taking in account the current proposal
More renaming and adding make_expected_from_call
Added default constructor, value_or, then, next, recover, operator==, ... and constexpr. constexpr doesn't works yet.

Use REQUIRES macro for SFINAE.
Fixed expected default constructor as constexpr.
Added list_initializer constructors
Remove non-constexpr aware implementation
Create README.md
