<td class="description last"><p>A function that creates a new build hasher.
Which in turn is a function that instantiates a hasher so genBuildHasher()()
instantiates a hasher. This is admittedly a bit over complex. The default
value is randomBuildHasher; the practical upshot here is that this construction
allows us to rerandomize the seed even when deepclone() or shallowclone() is used.
The downside is that supplying a simple hasher is quite a bit of work.</p>
<p><a href="module-hashing-Hasher.html">Hasher</a> contains an example of
how this property can be used to implement a hash table that
utilizes the object-hash library to hash unknown types.</p></td>
