Detailed Description

Utility class to find a location in the probe atlas that can be used to store a new probe in a specified subdivision level.

The allocation space is subdivided in target subdivision level and is multi layered. A layer has (2 ^ subdivision_lvl) ^ 2 areas.

All allocated probe areas are then process and the candidate areas containing allocated probes are marked as occupied. The location finder then return the first available area.
