 A drop-in replacement for ES native `Map` and `Set` with deep equality support for objects.
 
 ## Why?
@@ -81,3 +83,9 @@ Additional project-specific options:
 
 -   Don't mutate a map key (or set value) while still using the data structure. The internal representation is not affected by this mutation, so behavior may be unexpected.
 -   This implementation does not explicitly "handle" key collisions. However, with the default algorithm (MD5), even if a map contained one TRILLION entries, the probability of a collision on the next insert is only 0.000000000000001. If you need better odds, use SHA1, SHA256, etc.
