Add camera features to Sample app

[JonasVautherin]

Not all the features are implemented yet, but many of them are (like takePhoto, etc), as detailed in #5.

Would be nice to add them/some of them in the app already.

@ayameMBS Do you think you could have a look at this? So that the sample app would already have the structure to add the other features when they get implemented :-).

@JonasVautherin I can start working on this if that is okay. Let me know.

[JonasVautherin]

Thanks Sushma. Let's wait from a confirmation from @ayameMBS, maybe she already started that locally.

[ayameMBS]

Sorry for the late reply. No, I haven't start yet that implementation. So @Sushma7785 you can do it.
