Cache types

NOTE: WORK IN PROGRESS.

IMPORTANT!!! As of 2019-07-01 the matrix below describes next generation cache type mappings, which is a work in progress implementation.
---

A geocache may be of several types. Each type incurrs specific characteristics and/or rules that may apply to searching, finding and logging that type of cache.

This document describes the existing cache types across Opencaching sites.
