  20  * NOTES
  21  *   This implements the low-level and hi-level APIs for manipulating VARIANTs.
  22  *   The low-level APIs are used to do data coercion between different data types.
  23  *   The hi-level APIs are built on top of these low-level APIs and handle
  24  *   initialization, copying, destroying and changing the type of VARIANTs.
  25  *
  26  * TODO:
  27  *   - The Variant APIs do not support international languages, currency
  28  *     types, number formating and calendar.  They only support U.S. English format.
  29  *   - The Variant APIs do not the following types: IUknown, IDispatch, DECIMAL and SafeArray.
  30  *     The prototypes for these are commented out in the oleauto.h file.  They need
  31  *     to be implemented and cases need to be added to the switches of the  existing APIs.
  32  *   - The parsing of date for the VarDateFromStr is not complete.
  33  *   - The date manipulations do not support dates prior to 1900.
  34  *   - The parsing does not accept as many formats as the Windows implementation.
