An iterator class for walking over the elements of a sparsity pattern.
The typical use for these iterators is to iterate over the elements of a sparsity pattern (or, since they also serve as the basis for iterating over the elements of an associated matrix, over the elements of a sparse matrix), or over the elements of individual rows. There is no guarantee that the elements of a row are actually traversed in an order in which column numbers monotonically increase. See the documentation of the SparsityPattern class for more information.

Constructor. Create an iterator into the sparsity pattern sp
for the given global index (i.e., the index of the given element counting from the zeroth row).

Comparison. True, if both iterators point to the same matrix position.

Inverse of ==

Comparison operator. Result is true if either the first row number is smaller or if the row numbers are equal and the first index is smaller.
This function is only valid if both iterators point into the same matrix.

Return the distance between the current iterator and the argument. The distance is given by how many times one has to apply operator++ to the current iterator to get the argument (for a positive return value), or operator-- (for a negative return value).
