+@file sparse_array.h
+@brief Sparse array management
+
+The functions in this file manage sparse arrays. Sparse arrays are arrays with
+potential big dimensions, but with very few samples actually set. Such sparse
+arrays require allocating a low amount of memory, by just allocating memory
+for blocks of the array that are set. The minimum memory allocation unit is a
+a block. There is a trade-off to pick up an appropriate dimension for blocks.
+If it is too big, and pixels set are far from each other, too much memory will
+be used. If blocks are too small, the book-keeping costs of blocks will raise.
