@function @abstract Deletes a property from an object using a JSValueRef as the property key. @param ctx The execution context to use. @param object The JSObject whose property you want to delete. @param propertyKey A JSValueRef containing the property key to use when looking up the property. @param exception A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception. @result true if the delete operation succeeds, otherwise false (for example, if the property has the kJSPropertyAttributeDontDelete attribute set). @discussion This function is the same as performing "delete object[propertyKey]" from JavaScript.
