Description

Declares the Grid class.

This class provides functionality for setting up and accessing atoms on a grid for one domain decomposition zone. This grid is used for generating cluster pair lists for computing non-bonded pair interactions. The grid consists of a regular array of columns along dimensions x and y. Along z the number of cells and their boundaries vary between the columns. Each cell can hold one or more clusters of atoms, depending on the grid geometry, which is set by the pair-list type.
