// Class used for read-write the ALTRO data format //
/////////////////////////////////////////////////////

/*This class is an interface between the altro format file and the 
  user, and can be used in write or read mode
  In the write mode a new altro file is created and filled using the method FillBuffer().
  The name of the file is specified as parameter in the constructor as well as the type mode.
  In the Read mode the specified file is open and the values can be read using the
  methods GetNext() and GetNextBackWord().
  The first method is used to read the file forward while the second is used to read backward
