-There's a small problem here with the implementation: You can have a dimension tied
-to only one point while at the same time you can have a dimension sitting on this line.
-Since there's only *one* dimPoint for each point, this can be problematic...
-
-We solve this by allowing only *one* Dimension object to be attached to the Line,
-Arc, etc. and by giving the Dimension object a pointer to our endpoints.
-
-Problem still arises when we delete this object; The attached Dimension object will
-then have bad pointers! What it *should* do is delete the object if and only if this
-line is not attached to any other object. If it is, then one of those attachment
-points should be sent to the dimension object (done for position & endpoint).
-
-NOTE: The STL vector<T> *does not* take ownership of pointers, therefore is suitable
- for our purposes
-
-Also: It would be nice to have a preview of the dimension being drawn, with a modifier
-key to make it draw/show on the other side...
-
-TODO: Make Dimension preview with modifier keys for showing on other side
