Methods.Mutation.SUB_GATE causes error

[wagenaartje]

Causes following error every now and then:

Uncaught TypeError: Cannot read property 'ungate' of null

This code will create that error sometimes:

var x = new Architect.Perceptron(3, 10, 3); 
for(var i = 0; i < 10000; i++){  
  var keys = Object.keys(Methods.Mutation); x.mutate(Methods.Mutation[keys[ keys.length * Math.random() << 0]])
}; 
x.activate([1,0,1]);

Will be investigated!

The problem has been identified. Fix already created, doing some testing now. The probem was as follows

1. When removing a node, new connections would be created
2. If this happened to be a self connection, the connect() function would return the selfconnection
3. remove() function assumed all new connections would be ungated, and would gate them
4. Connections would be regated, while not removing the previous gate from this.gates
5. The ungate() process would remove the wrong gates, as one connection could be present twice

A simple fix: now checking for already-gated connections! Note to future self: if already gated, should move on to next connection.
