INTRODUCTION

This implements the COLA structure described in the paper "Cache Oblivious Streaming B-Trees" by Bender, Farach-Colton, et al.

We use mmap where possible and do k-way merges using a binary min-heap instead of binary merges.

NOT IMPLEMENTED

1. Values are not stored yet.
2. No fractional cascading or any other optimisation of queries.
3. Deamortisation (via background write thread) is also not implemented.
