Generating a model in the GWT interface for the "Shopping cart web app" example
log generates a model that demonstrates the bug:
1. The initial node has probabilities of 1.0 along both emitted edges, summing
to 2.0. They should sum to 1.0
2. Switching to "counts" view shows that the counts from the initial node along
both edges are 1 and 1, when they should be 30 and 15.
