My idea was to use some kind of tree structure, ie if you have the lines:

e4 c5 Nf3
e4 c5 d4

then that could be stored as

e4 c5 {Nf3,d4}

Which will save a lot of space for long lines where only the last few moves are
different.

The problem is that if they spilt too early the tree gets complex:

e4 c5 Nf3 Nc6
e4 c5 Nf3 d6
e4 c5 c4

turns into:

e4 c5 {Nf3 {Nc6,d6} , c4}

I think that is more compact, but I don't get the transpositions. I'm not sure
transposition are important anyway.
