Hello,

i am new to Digital Assitant and am currently trying to learn the OBotML language so I am building
a simple test skill to test transitions. 

My test case is this: I have one intent (Start - utterances:Hi,Hello, Hey), entities (Options - values: Option 1, Option 2, Option 3). I want the user to choose an option.
I check if the option is the one that I want chosen. If not..the user needs to choose again. 
If it is...continue.
