Element.ChangeTypeId

Description:
Changes the type of all elements in the given set.

Remarks:
In some cases, applying a change in type will result in a new element being created. The only active examples of this are when applying a normal wall type to a curtain panel, or converting such a wall back to a curtain panel. Then return map would have (original element id, new element id) pair(s). Note: this function needs an open transaction. Note: this function calls regeneration.
