Construct an object that implements Knearest from closures. We pass the tree so that we can infer the type of T.

fine is a function that gives the true distance between the point and the specified tree element.

broad is a function that gives the distance between the point and the closest point of a axis aligned rectangle. This function is used as a conservative estimate to prune out elements which minimizes how often the fine function gets called.

xline is a function that gives the distance between the point and a axis aligned line that was a fixed x value and spans the y values.

yline is a function that gives the distance between the point and a axis aligned line that was a fixed x value and spans the y values.

acc is a user defined object that is passed to every call to either the fine or broad functions.
