1) Default-constructor. Constructs a match result with no established result state (ready() != true).
2) Constructs a match result with no established result state (ready() != true) using a copy of a as the allocator.
3) Copy-constructor. Constructs a match result with a copy of rhs.
4) Move-constructor. Constructs a match result with the contents of rhs using move semantics. rhs is in valid, but unspecified state after the call.


a - allocator to use for all memory allocations of this container
rhs - another match_result to use as source to initialize the match_result with
