 +The application has two tabs "Create" and "Solve". In "Create" you can create and modify a Bayesian network, in "Solve" you can compute arbitrary probabilities using the network.
 Suppose you have a network with nodes A and B, where B depends on A. Suppose you have a network with nodes A and B, where B depends on A.
 To create the network, you need to: To create the network, you need to:
