HyperMap
A more generic version of BiMap (as seen in C++ Boost, Google), that associates two or more values together, such that only one is required to recall all others.

API
new HyperMap([iterable])
iterable is an Array or other iterable object whose elements are tuples (arrays).
Each item in each tuple is added to the new HyperMap. null is treated as undefined.
HyperMap.prototype.associate(items...)
Associates two or more items. Throws if less than two arguments are passed. If neither item exists in the HyperMap, creates a new association, otherwise adds the items to the existing association. Throws if you try to associate an item already present in another association.
Returns the HyperMap object.
HyperMap.prototype.disassociate(ref, itemsToRemove...)
Disassociate items. Selects an association based on ref, then removes items
from it as directed. Does nothing if an association is not found. If, as a result
of this method, an association now has less than two items, it is destroyed.
Returns the HyperMap object.
HyperMap.prototype.get(ref)
Returns the association that contains ref, as a Set, or undefined if not found.
HyperMap.prototype.has(ref)
Returns a boolean indicating whether ref is in the HyperMap.
