  - sumExpressionComplexity
```
public static int sumExpressionComplexity(ASTExpression expr)
```
    Calculate the boolean complexity of the given expression. NPath boolean complexity is the sum of && and || tokens. This is calculated by summing the number of children of the &&'s (minus one) and the children of the ||'s (minus one).
    Note that this calculation applies to Cyclomatic Complexity as well.
    
    Parameters:
    
    expr - control structure expression
    
    Returns:
    
    complexity of the boolean expression

    Overrides:
