#3 Hints

[Lucio Ferrao]

A two step hint feature. The first time the user hits
"Hint", pocketloop select the simplest next move and
hilight it's location without showing if it is a clear
or a set. If the user repeats the hint request,
pocketloop clears or sets the previously hilighted move.

Sure, I will have a look at the solving mechansim and make
the hint feature take the next step in the solving progress
(The Pocket Sudoku way).

The best thing would be to highlight the dot/number involved
in the step, right? Highligthing the connectors seems to
make it too easy...

Marking the dot/number seems ok for the basic movements, but
for the what-if steps we should mark the connector when
there are many numbers and dots involved.

I still have doubts about how to hint the merge result
changes that don't mark the "what-if" connector, but I think
we should still mark the "what-if" connector. Maybe the text
hint should be different.

One more thing, when there are multiple basic movements
available in the board (not sequencial movements), we should
hilight them all at the same time.
