*updates from CRAN feedback
ncmeta now provides support for dimensions that do not have explicit coordinates: dimension and variable tables now have information about “dimvals”, in the form of “dim_coord” and “coord_dim” i.e. if a variable is 1D and its name corresponds to a dimension name, then it is a rectlinear coordinate vector of that dimension. (The coordinates can be of type “char”, and that must be dealt with down stream as it now is in tidync).
new function nc_grids, the spaces available to variables
new function nc_axes, nc_axis for the instances of dimensions
nc_vars now returns only variables
First working version.
