Detailed Description

Class to store a list of counters.

A counter is a pointer to a function that returns the number of an alignable based on its id. The number of an alignable is given by its position within its parent. User gets a counter using its structure type via Counters::get(type). Each sub-system has its own concrete counter class implementation.
