* \file Much of the code for this file reader/writer was taken from
* the University of Iowa Psychiatry departments
* Imaging Group with permission of the author Vincent Magnotta
* \author Hans J. Johnson
* The University of Iowa 2002
* \brief This file was written as a modification to the itkMetaImageIO
* as a new method for reading in files from the Brains2Mask specification.
* Brains2Masks are specified as a single file. The first part of the file
* begins with an "IPL_HEADER_BEGIN" followed by ascii text describing the
* dimensions, and other important information about the data. The header
* information concludes with the "IPL_HEADER_END\n" identifier, and is immediatly followed by
* the binary portion of the file. The binary portion contains a binary octreeHdr
* consisting of 6 unsigned integers, followed by sequentially defined unsigned short integers
* representing (WHITE=1, BLACK=0, GRAY=2) colors. The GRAY color indicates that this is a branching node.
