Create a simple LLM chain

Create a chain that routes to emotion, then with the style generates four tweets.

Sub-issues

1. Should user select the emotion or the router randomly?
2. Why or why not?

@Frederickzoller In commit "two_emotions" the code randomly select two of the emotions and then two different styles correspond to each emotion.

Now, the prompt for the second style needs to be refined further so the difference between the styles is patently obvious, but the chain itself is working.

Also, we're working with a 1b model, pretty sure that after we use flash or another language model we'll get better performance for each style.

Once you have reviewed it and provided feedback, @Frederickzoller close the issue.

LLM chained need or just system prompt is ok?
