make a stand-along initialization for axes, separated from DimArray ==>
cleaner and can be used by Dataset
typo
raise an IndexError higher up in io.nc
axis checking was missing in AxesLocator
matlab-like indexing by put via np.ix_
solved bugs. hopefully final solution was found:
- put: convert slices to arrays and use np.ix_
- take: chain call

chain call is probably not very efficient, consider:
- checking if one list / np.ndarray is present
- if yes, also convert all to arrays
- eliminate singletons values with squeeze
