Method getPruned in ProbNetOperations prunes incorrectly the network Asia

[Manuel Luque]

When the method getPruned is invoked with evidence over variables "Tuberculosis" and "TuberculosisOrCancer" and interest variable "Dyspnea", the prune performed is incorrect.

Node "Tuberculosis" is pruned with a probability of 0.5362. However, node "Tuberculosis" should never be pruned, because its evidence acts jointly with the evidence on "TuberculosisOrCancer".

Look ProbNetOperationsTest. Method testPrune3. The remaining variables are:

Smoker Tuberculosis Cancer TuberculosisOrCancer Dyspnea Bronchitis

and there are no changes in the code

[Manuel Arias]

If the result of a method invocation is different with probability 0.5362 let here the code that reproduces the problem and reopen the issue.

[Manuel Luque]

A method "testGetPrunedMethodBN_Asia" has been added to class org.openmarkov.core.model.network.ProbNetOperationsTest.

Good work Manuel! I've just checked that VariableElimination using the prune works now correctly.
