/**
* This class is a stack frame that consists of
* information about the element currently being processed
* by a serializer. Consider this example:
* <pre>
* <A>
* <B1>
* </B1>
* <B2>
* </B2>
* <A>
* </pre>
*
* A stack frame will be pushed for "A" at depth 1,
* then another one for "B1" at depth 2.
* Then "B1" stackframe is popped. When the stack frame for "B2" is
* pushed, this implementation re-uses the old stack fram object used
* by "B1" to be efficient at not creating too many of these object.
*
* This is by no means a public class, and neither are its fields or methods,
* they are all helper fields for a serializer.
*
* The purpose of this class is to be more consistent with pushing information
* when a new element is being serialized and more quickly restoring the old
* information about the parent element with a simple pop() when the
* child element is done. Previously there was some redundant and error-prone
* calculations going on to retore information.
