Observation data setting.

[Choihojun]

I want to use phoenics with observation data. Can you tell me how to set observation data for sequential optimization example??

Specifically, I'm wondering how to put a value in square brackets here.

*It will be more good to understand if the example code had observation data

I found solution for how to use observations. I understood that the code generates pickle file in the folder. Like that, If we change the picklefile, we can use the observation data.
