Add AllOfArray matcher that verifies a value matches all member of some array/container/list/set/..., e.g:
EXPECT_THAT(1, AnyOfArray({1, 2, 3}))
In the simplest form this is identical to AnyOf(1, 2, 3). But unlike that one it works on containers.
Add AnyOfArray matcher that verifies a value matches any member of some
array/container/list/set/...
