      public class Header
      extends java.util.Hashtable<java.lang.Object,java.util.HashSet<java.lang.Object>>

  A Header is a data structure that contains all cell aspects by axis So, for a single cell it is possible to obtain all dimensions in the X, Y or Z axis.

  Note:
  The Z axis applies to all cells in a table
  The X axis applies to all columns in the same row
  The Y axis applies to all rows in the same column

  For this reason, a table contains 3 instances of Header. One for each axis The header is a Hashtable, keys in the Hashtable are aspect identity keys. values for each key are a HashSet of distinct values
