  This routine deals with moving data associated with quantities
 such as particles or rays, which do not have a fixed association
 with a specific point of the domain all through the time evolution.
 As they change their association from block to block, this routine moves
 them to the correct block and processor. 
 Depending upon whether the movement is due to regridding or not, this
 routine calls appropriate function to move the data as needed.


  dataBuf : the data structure containing the data of interest
              It is two dimensional real array, the first dimension
              represents properties associated with the data 
              structure, and 
              second dimension is index to individual elements in 
              the datastructure.

 propCount : number of properties for this datastructure 

  localCount : While coming in it contains the current 
               number of elements in the data structure mapped to
               this processor. After all the data structure 
               movement, the number might change, 
               and the new value is put back into it
  maxCount : This is parameter determined at runtime, 
             and is the maximum count of elements 
             that a simulation expects to have. 
             All the arrays  are allocated based on this number
  index_list : the list of indices of the data structure
  indexCount : the count of indices of the data structure
  regrid   : if true then regridding just happened and blocks have changed
