Determines the coverage of this {@link IAtomContainer}'s 2D coordinates. If all atoms are
non-null and have 2D coordinates this method will return {@link CoordinateCoverage#FULL}. If
one or more atoms does have 2D coordinates and any others atoms are null or are missing 2D
coordinates this method will return {@link CoordinateCoverage#PARTIAL}. If all atoms
are null or are all missing 2D coordinates this method will return {@link CoordinateCoverage#NONE}. If
the provided container is null {@link CoordinateCoverage#NONE} is also returned.

@param container the container to inspect

@return {@link CoordinateCoverage#FULL}, {@link CoordinateCoverage#PARTIAL} or {@link CoordinateCoverage#NONE}
depending on the number of 3D coordinates present
