README example code gives error

[lorenzwalthert]

Thanks for this useful package! I ran into an error from running the code in the README. Apparently, the method new() for Logger does not take a file argument:

library(RestRserve)
logger = Logger$new(level = TRACE, file = "")
#> Error in .subset2(public_bind_env, "initialize")(...): unused argument (file = "")
# ...

Thanks for reporting. Hopefully this will soon fixed by merging dev branch.
