/// <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 ) );
