/**
* <h1>JEBML Intro</h1>
* <hr>
* <p>The following are the basic steps of how reading in JEBML works.</p>
* <ul>
* <li>1. The EbmlReader class reads the element header (id+size) and
* looks it up in the supplied DocType class.
* <li>2. The correct element type (Binary, UInteger, String, etc) is
* created using the DocType data, BinaryElement is default
* element type for unknown elements.
* <li>3. The MatroskaDocType has the ids of all the elements staticly
* declared.
* <br>So to easily find out what an element is, you can use some code
* like the following code
* <p>
* <code>
* Element level1; <br>
* // ... fill level1 <br>
* if (level1.equals(MatroskaDocType.SegmentInfo_Id)) { <br>
* // Your Code Here <br>
* } <br>
* </code>
* </p>
* <li>4. To get the actual data for an Element you call the readData
* method, if you just want to skip it use skipData().
* <li>5. MasterElements are special, they have the readNextChild()
* method which returns the next child element, returning null
* when all the children have been read (it keeps track of the
* current inputstream position).
* <li>The usage method for JEBML is very close to libebml/libmatroska.
* </ul>

/**
* A LinkedList implementation which holds instances of type

*
* <p>Using this implementation allows you to get java.util.LinkedList
* behavior (a doubly linked list, with Iterators that support insert
* and delete operations) without incurring the overhead of creating
* <tt>Node</tt> wrapper objects for every element in your list.</p>
*
* <p>The requirement to achieve this time/space gain is that the
* Objects stored in the List implement the <tt>TLinkable</tt>
* interface.</p>
*
* <p>The limitations are that you cannot put the same object into
* more than one list or more than once in the same list. You must
* also ensure that you only remove objects that are actually in the
* list. That is, if you have an object A and lists l1 and l2, you
* must ensure that you invoke List.remove(A) on the correct list. It
* is also forbidden to invoke List.remove() with an unaffiliated
* TLinkable (one that belongs to no list): this will destroy the list
* you invoke it on.</p>
