-/// <summary>
-///   Calculates a hash value for an arbitrary set of binary data.
-/// </summary>
-/// <remarks>
-///   This method produces a 32 bit hash result from an array of source data, and
-///   is suitable for generating string hashes.  It can also be used to generate
-///   hashes for struct-style data (example below).  This is the method used by the
-///   <c>std::string / std::wstring</c> overloads of the <see cref="CommonHashes"/>
-///   class.
-///
-///   Note:
-///   This method is an ideal use for any set of data that has five or more
-///   components to it.  For smaller data types, such as Point or Rectangle
-///   structs for example, you can use the int32 / uint32 hashs for faster
-///   results.
-/// </remarks>
-/// <example>
-///   This is an example of taking the hash of a structure.  Keep in mind that
-///   this method only works reliably for structures that do not contain objects
-///   or pointers.
-///   <code>
-///		struct SomeData
-///		{
-///			int val;
-///			double floats[3];
-///			char id[4];
-///		};
-///
-///		SomeData data;
-///		uint32 hashval = Hash( (const char*)&data, sizeof( data ) );
-///   </code>
