`find` overloads

== Synopses

Declared in `<bslstl_hashtable.h>`

Return the address of a link whose key has the same value as the specified `key` (according to this hash‐table's `comparator`), and a null pointer value if no such link exists. If this hash‐table contains more than one element having the supplied `key`, return the first such element (from the contiguous sequence of elements having the same key).

Return the address of a link whose key is equivalent to the specified `key` (according to this hash‐table's `comparator`), and a null pointer value if no such link exists. If this hash‐table contains more than one element having the supplied `key`, return the first such element (from the contiguous sequence of elements having the same key). The behavior is undefined unless `key` is equivalent to the elements of at most one equivalent‐key group.
