   adjust xcm of each cluster due to box deformation

   called by various fixes that change box size/shape

   flag = 0/1 means map from box to lamda coords or vice versa

   NOTE: cannot do this by changing xcm of each body in cluster

         or even 1st body in cluster since POEMS does not observe xcm

	 but only sets xcm

         or even 1st body in cluster

	 b/c POEMS does not see xcm but only sets xcm

	 so dilation needs to be coordinated with POEMS

	 this routine does nothing for now
