Disable tensors (so it's just an RNN, not RNTN)

There seems to be a bug in DeepLearning4j with the tensors:
https://groups.google.com/forum/#!topic/deeplearning4j/WBQI-NscDRA

They give:
Exception in thread "main" java.lang.AssertionError: Expected a column vector
	at org.deeplearning4j.nn.linalg.FloatTensor.bilinearProducts(FloatTensor.java:551)
	at org.deeplearning4j.rntn.RNTN.forwardPropagateTree(RNTN.java:690)

Use toy.xml as passage
