<p>Each data source has a set of dimensions available for use by variables. Each grid is
an n-dimensional space available for use by 0, 1 or more variables. A grid only really
exists if variable is defined for it, and 'grid' is an implicit entity not an explicit
part of the NetCDF API definition. The Unidata pages refer to "shape", which is more or less what
we mean by "grid".</p>
