#230 fixed

• Leader: new property AssociatedAnnotation
• CadLeaderTemplate: implementation added: Build

The annotation is always present? if it is, it would be good to have an else with a log using the notification method so the user knows why the annotation is missing when the reader finishes.

[mme1950]

you provided the getTableReference method for table references. Shoud we implement a similar method for Entity references?

[DomCR]

I'm not 100% sure but I think that some entity references may have a null value, so I'm not sure that this method needs to be implemented, that's why I'm asking if the AssociatedAnnotation can be null or not, because if it can, there is no need to notify anything.

[mme1950]

Actually, I do not know. I suppose it is null when no annotation is associated with the leader.
I currently cannot check in AutoCAD, whether it is possible to create a LEADER without annotation.
The annotation (typically an MTEXT) of a LEADER appears as a separate object in the DWG.

[mme1950]

... because if it can, there is no need to notify anything.

I thought the notification is issued when a reference was read that cannot be resolved.

[DomCR]

Exactly, that's why I've asked if this parameter is optional, because if it is, not finding the value or assigning a null value is a valid resolution for the reference and should not be notified as an error or warning.

[mme1950]

We checked it with AutoCAD:
It is possible to create a LEADER without annotation. Then the field does not appear in DXF.
In this case the AssociatedAnnotation property should be null.

Perfect! merging this PR.

Good work!!
