// 
//   Define a dfad data Info.
//   It permits access to read it sequentially from a
//   point, asking for:
//   a feature : 2 words
//   a coord   : a word
//   checksum  : a word
//   a zero word.
//
//   - setPointerToWord(int i = 0); i <= 601 : sets the pointer to word i
//   - getFeature(pfeature): gets next feature data size (two words)
//   - getCoord(pCoord): gets next coord data size ( word)
//   - getWords(pWords, howMany): gets howMany words
//
//  For more details, see dfad_main.doc
