C++ concepts: SeedSequence

A seed sequence is an object that produces unsigned integer values $i$ in the range $0 \leq i < 2 32$ based on a consumed range of integer data.

S is a SeedSequence.
q is an object of S and r is a potentially constant object of S.
T is the result_type.
ib,ie are InputIterators with a value_type of unsigned integer values of at least 32 bits.
il is an std::initializer_list<T>.
rb,re are modifiable RandomAccessIterators with a value_type of unsigned integer values of at least 32 bits.
ob is an OutputIterator.

Expression	Type	Notes	Complexity
`S::result_type`	`T`	Unsigned integer of at least 32 bits	compile-time
`S()`		Creates a seed sequence with the same default values as other objects of type `S`	constant
`S(ib,ie)`		Creates a seed sequence based on the supplied input bits by $[ib, ie)$	$O(ie-ib)$
`S(il)`		The same as `S(il.begin(), il.end())`
`q.generate(rb,re)`	`void`	Fills $[rb, re)$ with 32-bit quantities depending on the initial supplied values and potential previous calls to `generate`. If it does nothing.	$O(re-rb)$
`r.size()`	`size_t`	The amount of 32-bit integers copied by `param`.	constant
`r.param(ob)`	`void`	Copies 32-bit values to `ob` that would reproduce the current state of the object if passed to a constructor of `S`.	$O(r.size())$
