 /** Parses and contains the parsed data
 Also implements data accessor functions for tree traversal and value getters
 The data pointer passed in the constructor is assumed to be valid throughout the object's life. Care must be taken not to initialize from a temporary.
+The parser decomposes the input data into a tree of tags that is stored as an array of cFastNBTTag items,
+and accessing the tree is done by using the array indices for tags. Each tag stores the indices for its parent,
+first child, last child, prev sibling and next sibling, a value of -1 indicates that the indice is not valid.
+Each primitive tag also stores the length of the contained data, in bytes.
