Momento on the Network

[toddpi314]

Having issues getting the load method to work on a serialized network (configuration).

When using the load, I am seeing a nodejs process abort.
After investigating, I can bypass the abort by editing the NNet::CreateFromFile method in the fan-create class impl.

Handle<Value> NNet::CreateFromFile(const Arguments &args)
{
    HandleScope scope;
    if (args.Length() != 1 || !args[0]->IsString())
        return VException("usage: new FANN.load(\"filename.nnet\")");

    char name[4096];
    String::Cast(*args[0])->WriteAscii(name, 0, 4096);
    // name[4095] = 0;  <=== comment this out!  

    FANN = fann_create_from_file(name); 

    return Undefined();
}

Beyond this, once the wrapped fann instance is available in Node, i get segment faults when attempting to interact with it:

Has anyone on the author team attempted to read/write a network?

Yes, and it works here on 3.8.0-30-generic x86_64 linux kernel. That's why we probably missed it. But it is a bug all right.

I believe it's now fixed by #9.
