Investigate the options for the default label placement on edges

[david-istvan]

Placing labels to the source/target end by default would come in handy in some cases. For example, on Decision output edges.

This is indeed possible. From the official documentation:

Edge Labels. Edges can have from zero to three labels. By default they have a single which will be placed at its center. You can delete it and/or add labels to be shown at the beginning (near the source) or end (near the target) of the edge. In all cases, the configuration is the same as for all labels. Note that currently only the center label (if present) is editable if a Direct Edit tool is associated to the edge mapping.

Caveat: the direct edit tool can't be used for source/target labels.

The workaround is quite elaborate with custom edit parts: https://www.eclipse.org/forums/index.php/t/1075980.

This won't be implemented in the 0.2. Tentatively scheduled for 0.3.
