Description

Dear all,

Can you please provide a documentation regarding creating custom Iterators. For example, explain the functionality of the functions inside SortedKeyValueIterator and how to override those functions.

Please explain how these functions are executed (which class calls these functions when the iterator executes).

I would appreciate if these changes are made in your future documentations as this would help developers who are new to accumulo to quickly get started on writing their own custom iterators which is an essential part of accumulo.
