Address any pain points with Kotlin

[NoahAndrews]

Before anyone writes any code for this, write an OpMode with Kotlin and identify any pain points here, such as needing to use ? excessively. Also test things like Vuforia. If you have any ideas for how to improve things, submit them here.

I've started integrating Kotlin into Pattonville Robotics's workflow and I haven't run into any problems so far. I've found that the lateinit keyword for fields is useful to convey to the compiler that those fields are non-null, but shouldn't be accessed before being initialized.
