Remove/change R6APIController

Hi. I was trying to use your API for my project and I encountered a problem where I can't direct to any urls from my own Controllers when the application is running. I am pretty sure that is because of the fact that in your R6APIController you are using class-level RequestMapping("/"), which seems like can't be bypassed anyhow. Moreover, I don't really see any need in this Controller, so I would suggest to simply remove it. But in case you want to keep it, then it is important to change the class-levl RequestMapping value to something else. However, if you know any possible way to bypass this this Mapping and be able to use other Controllers, then it would be cool if you could tell how to do that
