This container class permits one to select a subset of a point set.
This is done by selecting a range or providing an array of either point or coordinate indices. A typical application of a range selection is to make the number of points or the dimension finite. It is also possible to provide, for example, a random permutation in the selection of components. It is possible also to take projections of coordinates for selected dimensions.
Selecting a new subset of points or coordinates overwrites the previous selection. The specification of a subset with respect to the points is independent from selecting a subset with respect to the coordinates. The number of points and the dimension are adapted to the current selection and all indices still start from 0, i.e., the subset works just like an ordinary point set.
When the points or coordinates ranges are changed, existing iterators become invalid. They should be reconstructed or reset to avoid inconsistencies.
