/*
  This class implements a simple book keeping system for the current
  input box. In general there are three different input boxes which
  are relevant:
 
   1. The global box give by the complete dimensions of the grid.
 
   2. The input box given explicitly by the BOX keyword. That BOX will
       apply to all following FIELD properties, and it will continue
       to apply until either:
 
          - ENDBOX
          - A new BOX
          - End of current section
 
       is encountered.
 
   3. Some keywords allow for a Box which applies only to the elements
      of that keyword.
