Remove need for AxExecutionViewMgr.ConnectExecutionView() in custom UI

[JonP]

In a custom UI I currently need to have two AxSequenceView controls to display sequences:

1. Connected to the AxSequenceFileViewMgr. This shows the static view of the sequence file and is where you can attach the debug context menu to loop selected steps etc.
2. Connected to the AxExecutionViewMgr. This shows exactly the same view of the sequence file during execution, with just an additional "Status" column with the result status of each executed step. You can toggle a breakpoint by clicking in the margin but can not select steps or operate a debug context menu here.

Of course I could display both views in the UI but this feels illogical for the user, so I prefer to show only one and switch between them according to context. However this presents problems:

1. As this post (not one of mine!) says, you have to display the SequenceFileViewMgr view after loading a program because the Execution View would be blank, and then switch to the Execution View when the program is running.
2. You have to switch back to the Sequence File view when the program ends in order to re-enable the debug context menu. This means that the step statuses disappear before the user has a chance to look at them in detail. It also means that the new view is not aligned to the execution view (i.e. the first visible step is different) - this may be solvable with a lot of programming but I haven't worked out how!.

It feels to me that it would be better for the API to provide a single view of the sequence file that has the debug facilities available, with a status column that is blank (and gets reblanked at the start of every execution). My UI code would be considerably simplified!
