A simple example of using dropbox sdk on android with Kotlin.

[Sererim]

I am new to writing Android applications and have found it difficult to navigate Java examples. I believe that providing a simple usage example of the Dropbox SDK with Kotlin will make it easier for others to use this API in the future, as documentation for Kotlin is currently lacking (in my opinion and dropbox links this repository for guidens). The existing Android example is overwhelming, so a straightforward example in Kotlin would be beneficial.
