/*
 * VARIANT
 *
 * Copyright 1998 Jean-Claude Cote
 *
 * NOTES
 *   This implements the low-level and hi-level APIs for manipulating VARIANTs.
 *   The low-level APIs are used to do data coercion between different data types.
 *   The hi-level APIs are built on top of these low-level APIs and handle
 *   initialization, copying, destroying and changing the type of VARIANTs.
 *
 * TODO:
 *   - The Variant APIs are do not support international languages, currency
 *     types, number formating and calendar.  They only support U.S. English format.
 *   - The Variant APIs do not the following types: IUknown, IDispatch, DECIMAL and SafeArray.
 *     The prototypes for these are commented out in the oleauto.h file.  They need
 *     to be implemented and cases need to be added to the switches of the  existing APIs.
 *   - The parsing of date for the VarDateFromStr is not complete.
 *   - The date manipulations do not support date prior to 1900.
 *   - The parsing does not accept has many formats has the Windows implementation.
