From ddff1d83531447329ca384589c31bab8cf408c95 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Moved Shared.cs from Nuclex.Math to Nuclex.Support because
 this class can be quite useful in other locations as well; added CPL
 copyright header to all files in Nuclex.Math; fixed copyright date in
 AssemblyInfo.cs of Nuclex.Math and Nuclex.Support
