class IntArray
/*
   This class implements an array of integers.
 DESCRIPTION :
   An IntArray stores its coefficients in an array 'value' of size 'size'.
 TASKS :
   - storing and reterning coefficients (method 'at') ;
   - appending another IntArray to itself ;
 REMARK :
   see Remark 2 in file "floatarry.hxx".
