-#### Build Message with Arguments(Auto Check).vi
-
-- <B>For Example:</B>
-
-If <b>State with Arguments</b> input is "API: DoSth"
-- <b>Arguments ("")</b> input is "Arguments"
-- <b>Target Module ("")</b> input is "Callee"
-Then result string is "API: DoSth >> Arguments" as no message symbol is detected.
-
-If <b>State with Arguments</b> input is "API: DoSth >> Arguments -> Callee"
-- <b>Arguments ("")</b> input is "NewArguments"
-- <b>Target Module ("")</b> input is ""
-Then result string is "API: DoSth >> NewArguments -> Callee"
-
-If <b>State with Arguments</b> input is "API: DoSth >> Arguments -> Callee"
-- <b>Arguments ("")</b> input is "NewArguments"
-- <b>Target Module ("")</b> input is "NewCallee"
-Then result string is "API: DoSth >> NewArguments -> NewCallee"
-
-If <b>State with Arguments</b> input is "API: DoSth >> Arguments -> Callee"

-- <b>State with Arguments</b>: Input Message which might contain Arguments or target Module
-- <b>Arguments ("")</b>: The arguments which will be used to replace arguments in <b>State with Arguments</b>. if empty, no arguments will be included in output strings.
-- <b>Target Module ("")</b>: The target which will be used to replace target in <b>State with Arguments</b>. if empty, target in <b>State with Arguments</b> will be used.
-- <b>State with Arguments</b>: String stands for state with arguments
