示例1: CallFunctionInScript
/// <summary>
/// Call a function by passing in all the values.
/// </summary>
/// <param name="ctx">The context of the runtime</param>
/// <param name="functionName">The name of the function to call.</param>
/// <param name="paramListExpressions">List of parameters as expressions to evaluate first to actual values</param>
/// <param name="paramVals">List to store the resolved paramter expressions. ( these will be resolved if paramListExpressions is supplied and resolveParams is true. If
/// resolveParams is false, the list is assumed to have the values for the paramters to the function.</param>
/// <param name="resolveParams">Whether or not to resolve the list of parameter expression objects</param>
/// <returns></returns>
