"""Simpleperf gui reporter: provide gui interface for simpleperf report command.
There are two ways to use gui reporter. One way is to pass it a report file
generated by simpleperf report command, and reporter will display it. The
other ways is to pass it any arguments you want to use when calling
simpleperf report command. The reporter will call `simpleperf report` to
generate report file, and display it.
