ncdfCF 0.3.0

• Function peek_ncdf() returns quick-view information on a netCDF resource.
• String-valued labels for discrete and generic numeric axes are now
  supported, including multiple label sets per axis. The labels are
  associated with an axis rather than a data variable (as the CF
  documents imply) and the axis must be explicitly defined (as the CF
  documents imply but not explicitly state, and it is missing from the
  example given).
• Functions makeMemoryGroup(), makeLongitudeAxis() and
  makeLatitudeAxis() added to create scaffolding for new CF objects.
• NCGroup::unused() method identifies unused NCVariables to aid in
  finding issues with netCDF resources.
• print() method for NCVariable and NCDimension.
• Method CFObject$fullname added, giving fully-qualified CF object name.
• "Axis" associated with bounds variable is no longer created.
• NASA level-3 binned data (L3b) is now supported.
• Reference to a containing NCGroup moved down to CFObject for CF
  objects.
• Minor code fixes.
• Documentation extended and formatting fixed, new vignette.
