API is not clear

[bleucitron]

The API as described in the docs could use some clarity.

Some methods (removeTrailingSlashes, simpleObjectDeepClone,...) are clearly utils and could be stored under utils.

"Request" methods (not the OsmRequest instance) are not coherent. The write methods require an instance of osm-auth, but no endpoint is required (unlike fetch methods). How do you then point to the osm dev instance with write method ?

Maybe clarify the docs ?
