* Make `require` statements assume lib/ is in the $LOAD_PATH * Remove the methods in the Metrics::Instruments module -- there isn't a big benefit of using the `register` methods over just having the methods create instances of the objects that are needed right there. This also makes it possible to have more than one instance of `Metrics::Agent` in a process. * Remove base classes for instruments and statistics -- these don't really provide value in ruby
…unit conversion internally, initial implementation of timer, more specs.
Changes: * new register functions for exponential histogram * aliased agent.histogram to agent.uniform_histogram * added spec tests for exponential sample storage and histogram * updated README.md
…erms from the JVM metrics package, updated tests and examples to match this change.
