A helper method used to find out whether or not a certain input token has to be case-sensitively matched.

@param array<int, bool>|bool $caseSensitive global case sensitiveness or an array of booleans, whose keys should match
the ones used in $others. If any is missing, the default case-sensitive
comparison is used
@param int                   $key           the key of the token that has to be looked up

@return bool
