*	+ core,spray: create and implement http server metrics for spray, related to #56	Ivan Topolnjak	2014-07-23	4	-37/+110

*	! all: refactor the core metric recording instruments and accomodate UserMetrics	Ivan Topolnjak	2014-07-03	4	-29/+18
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This PR is including several changes to the kamon-core, most notably: - Formalize the interface for Histograms, Counters and MinMaxCounters. Making sure that the interfaces are as clean as possible. - Move away from the all Vector[Measurement] based Histogram snapshot to a new approach in which we use a single long to store both the index in the counts array and the frequency on that bucket. The leftmost 2 bytes of each long are used for storing the counts array index and the remaining 6 bytes are used for the actual count, and everything is put into a simple long array. This way only the buckets that actually have values will be included in the snapshot with the smallest possible memory footprint. - Introduce Gauges. - Reorganize the instrumentation for Akka and Scala and rewrite most of the tests of this components to avoid going through the subscription protocol to test. - Introduce trace tests and fixes on various tests. - Necessary changes on new relic, datadog and statsd modules to compile with the new codebase. Pending: - Finish the upgrade of the new relic to the current model. - Introduce proper limit checks for histograms to ensure that we never pass the 2/6 bytes limits. - More testing, more testing, more testing. - Create the KamonStandalone module.
