Info about mapping array axes to another order.
Internal
AxesMapping holds the information about mapping axes to another order. It can be constructed by AxesSpecifier by applying a shape to the axes specification.
AxesMapping is thereafter used to map positions, shapes, and slices to the new axes or backwards.
Caution: Shapes and positions are both represented by class IPosition; However, they have to be treated differently in this class, because removed axes for a position have value 0, while for a shape they have value 1; Hence there are different functions for them and the user has to take care that the correct function is called;
The class encapsulates the mapping functionality. It is meant as a helper class for casacore's SubLattice.

The default constructor creates empty maps.

Construct it with the mapping from old to new axes order.
A value of -1 means that the old axes is ignored in the new one. Another value gives the new axis number.
It determines if axes are removed and/or reordered.

Get the mapping of old->new.
The length of the resulting IPosition is the dimensionality of the original lattice. A value of -1 indicates that the corresponding axis in the original lattice is removed. Another value is the axis number in the new lattice,

Get the mapping of new->old.
The length of the resulting IPosition is the dimensionality of the new lattice. Its values give the axes in the original lattice.
