GoAnalysis.getLiberties() method
Returns a number for each point, representing how many open nodes its network/chain is connected to. Empty nodes and dead nodes are shown as -1 liberties.
Takes an optional boardState argument; by default uses the current board state.
For example, a 5x5 board might look like this. The chain in the top-left touches 5 total empty nodes, and the one in the center touches four. The group in the bottom-right only has one liberty; it is in danger of being captured!
[ [-1, 5,-1,-1, 2], [ 5, 5,-1,-1,-1], [-1,-1, 4,-1,-1], [ 3,-1,-1, 3, 1], [ 3,-1,-1, 3, 1], ]
