Visual mode for Swap commands

[Nekketsu]

Would it be possible to add support for the Swap commands in visual mode?

I think that sometimes it's useful to have a visual indicator of what we are going to swap.
I'd like to select visually a function, and being able to swap it with another one, while having the original one selected. It is the way that syntax-tree-surfer used to work, and I think it was quite usefull.

Note this relates to #39 - seems to be the same underlying desire

Now that Treewalker has the select option, this is seeming more relevant. I guess Treewalker just had to take its time to come around to your vision :D

Let me ask for a bit of clarification about your ask:

Say I have a node selected. I do a :Treewalker SwapDown, and it performs the normal swap down behavior, but once that's done, the originally selected node (which is now below the node that was formerly under it), is still selected.

Is this what you're thinking @Nekketsu?

Exactly, this is what I am thinking.

For me it should be like I am moving the selected node. Every time I press they keymap for :Treekalker SwapDown, I'd like to see that the selected node moves down (swap down) to the position of the next node, and it keeps selected. Then, I'd be able to press as many times as I want this keymap to continue moving down the selected node.
