Module perf_trace

This module contains macros for logging to stdout a trace of wall-clock time required to execute annotated code. One can use this code as follows:

use ark_std::{start_timer, end_timer};
let start = start_timer!(|| "Addition of two integers");
let c = 5 + 7;
end_timer!(start);

The foregoing code should log the following to stdout.

Start: Addition of two integers
End: Addition of two integers... 1ns

These macros can be arbitrarily nested, and the nested nature is made apparent in the output. For example, the following snippet:

use ark_std::{start_timer, end_timer};
let start = start_timer!(|| "Addition of two integers");
let start2 = start_timer!(|| "Inner");
let c = 5 + 7;
end_timer!(start2);
end_timer!(start);

should print out the following:

Start: Addition of two integers
    Start: Inner
    End: Inner               ... 1ns
End: Addition of two integers... 1ns

Additionally, one can use the add_to_trace macro to log additional context in the output.
