Indexing functions for IPosition's Convert between IPosition and offset in an array.
The offset of an element in an array is the number of elements from the origin that the element would be if the array were arranged linearly. The origin of the array has an offset equal to 0, while the "top right corner" of the array has an offset equal to one less than the total number of elements in the array.
Two examples of offset would be the index in a carray and the seek position in a file.
