<p>A data structure that holds a sorted collection of values, and supports efficient insertion, deletion, sorted iteration, and min/max finding. Values may sorted either based on their natural ordering, or on a key function (specified as an argument to the search tree's constructor). The search tree may contain duplicate values (or multiple values with equal keys) -- the ordering of such values is undefined.</p>
<p>This implementation was made with efficiency in mind. In particular, it is more than twice as fast as the other native-Python implementations I tried (which all use objects to store search tree nodes).</p>
