Improve the story of using this from inside composable functions

[StylianosGakis]

Currently, when inside a top level function (ofter true for composable funs) the api forces you to pass a tag manually, sort of killing the simplicity of "I just want to log something here" this library usually provides.
With that said, as far as I am aware there is no way to simply by default take the function name as the tag or something similar, so maybe this isn't a solvable problem and we simply have to pass a tag ourselves in such cases. If that's the case feel free to simply close this issue.

Maybe we could fallback to Timber-esque getting file name from Exception in this case?

Another good workaround is to define a live template, for example clog (as in, compose log):

logcat("$methodName$") { "$CODE$" } and then you set methodName's expression to kotlinFunctionName().

This live template would prefill method name, allowing you to just as easily start logging in couple keystrokes.
