// Tonko's data format for now...
//
// rdo data as follows:
// ------------------------
// | rdoHeader            |
// ------------------------
// | altroData[] fee 1    |
// | altroData[] fee 2    |
// | ...                  |
// | altroData[] fee n    |
// ------------------------
// | rdoTrailer           |
// ------------------------
//
// For the ALTRO data format see the altro user manual.  The data from the altro
// is packed into 64 bit data words.  4 10 bit altro words are packed into the low 40 bits
// of each data word.  The high 24 bits are used for status information
// 
// The offset to the end of the altro data block is obtained is obtained from the rdoHeader
// There is way to navigate through the altro data without decoding each banks starting
// at the end
//
