:memo: cleanup after #650 As <iostream> is not included in json.hpp any more, all code examples need to include <iostream> now. 2017-07-09 09:51:38 +00:00			`#include <iostream>`
:bookmark: set version to 3.1.0 - updated documentation wrt. new repository layout - temporarily switched off Homebrew --HEAD building (can only be switched on after release) - set copyright date to 2018 2018-02-01 21:20:26 +00:00			`#include <nlohmann/json.hpp>`
