Detailed Description

The PLUTO Grid structure contains information pertaining to the computational mesh in a specific 1D coordinate direction. Since PLUTO assumes a logically rectangular system of coordinates, the whole computational domain is obtained as the cartesian product of 2 or 3 grid structures.
In parallel, each processor owns a different portion of the domain and the grid structures will be different. For this reason, in the following member description, we use the word "global" or "local" to refer the the whole computational domain or to the sub-domain owned by a single processor.

Similarly, variables ending with a "glob" suffix are intended to be global, i.e., they refer to the whole computational stencil and not to the local processor sub-domain.
