// Class: Variant

// Basic variant class.
//
// Programmer: Cyrus Harrison
// Creation: December 10, 2007
//
// Modifications:
// Brad Whitlock, Tue Jan 6 15:16:19 PST 2009
// I added methods that let it read/write itself using Connection.
//
// Kathleen Biagas, Wed Jul 13 10:15:33 PDT 2011
// Added ConvertToString, takes a basic type and returns a string
// respresentation (useful for logging).
//
// Cyrus Harrison, Wed Jan 9 14:16:38 PST 2013
// Added conversion helpers for numeric types (ToFloat,ToFloatVector,...etc)
