Profiler
========
Easy, targeted Ruby profiling
Overview
--------
Profiler lets you easily measure the time spent in specified code paths.
If a certain code path is taking some time, call `Profiler.start` before it, `Profiler.stop` after it, and `Profiler.check` at significant checkpoints throughout it. For each edge (where an edge is a path between two `Profiler.check` calls), Profiler will print the cumulative time spent in the path and the number of times it was called:
```ruby
class MyClass
def initialize
Profiler.start
do_something
Profiler.stop
end
def do_something
# ...
Profiler.check
# ...
Profiler.check
# ...
100.times do
Profiler.check
# ...
end
end
end
```
```
