Removes elements from the container that are equal to the given values according to the less comparator. One element is removed for each value given which is in the container. If allowDuplicates is true, duplicates are removed only if duplicate values are given.
Complexity: m log(n) (where m is the number of elements to remove)
Example: std.algorithm, std.container;
auto rbt = redBlackTree!true(0, 1, 1, 1, 4, 5, 7); rbt.removeKey(1, 4, 7); assert(equal(rbt[], [0, 1, 1, 5]));
rbt.removeKey(1, 1, 0); assert(equal(rbt[], [5])); --------------------
