Deconstruct VP tree back into list. The order of elements in the original list is not preserved.
Find all items in the tree @c(tree) closer to @c(item) than @c(threshold). @c(item) and elements of the tree must belong to a metric space with @c(distance) as a metric function. Optional @c(key) function can be used to calculate a distance between two objects in the following way: @c(ρ(x,y) = distance (key(x), key(y))).
Make vantage point tree from a set @c(list) using a distance function @c(distance). Optional @c(key) function can be specified as a mapping between elements in @c(list) and elements in your metric space, so @c(ρ(x,y) = distance (key(x), key(y))) where x and y are in the @c(list).
Return element in the @c(tree) which is the closest element to @c(item). @c(item) and elements of the tree must belong to a metric space with @c(distance) as a metric function. Optional @c(key) function can be used to calculate a distance between two objects in the following way: @c(ρ(x,y) = distance (key(x), key(y))).

Divide a set in two halves depending on the value of predicate function
Return median value for a list
Pick a random value from a list and return this value and a new list with this value removed.
True if this node is a leaf
