    Description copied from interface: IEvaluator
    
    Evaluate an expression as a boolean response.
    
    Specified by:
    
    evaluate in interface IEvaluator
    
    Parameters:
    
    expression - the expression to evaluate
    
    values - the variables that the expression can evaluate against
    
    Returns:
    
    true if the expression evaluates to truthy value.

  - objectToBoolean
```
public static boolean objectToBoolean(Object obj)
```
    Given an input convert to a boolean expression.
    As Java doesn't have inherit truthiness such as JavaScript. We want to simulate it here, we will convert the following to inputs, all other inputs are true.
    
    null - All null values are false.
    
    boolean = All booleans are returned as they are.
    
    0 = All numbers are true, except 0 which is false
    
    "true" = A string of the value "true" (ignoring case) is true, all other strings are false.
    Parameters:
    
    obj - the value to convert
    
    Returns:
    
    the value as a boolean
