Introduction

In this article, I would like to introduce and explain a data structure I have written in C#. This structure has the ability to store items sorted along "N" dimensions. It is similar in concept to a k-d tree (see Wikipedia), but it is NOT implemented as a binary tree. It branches relative to the number of dimensions its items are being sorted upon.

I developed the structure entirely on my own accord, and since I could not find another implementation like it, I am taking the liberty in giving it a name. I have called the structure an "Omni-Tree".

	// This is a derivative work. The logic of this function comes from a switch statement found inside the
	// Lucene.Net library. The documentation of the conversion of characters is quite impressive
