All the dll are required in the executable folder, however only the CSDupuitNet.dll needs to be referenced by the CS application.

USAGE:

   string fileName = "c:/CSDup/Test";
   var dWrap = new dupuitWrapper();				! create wrapper instance
   int handle = dWrap.CreateDupuitHandle();		! create handle \ dupuis structure (multiple times)
   dWrap.calculate(fileName, handle);			! calculate from filename and corresponding structure handle.
