Examining the existing documentation over the standard Go documentation
server revealed some serious formatting flaws. Everything should be
readable now.
- Comments are migrated from ``/* */`` to ``//`` per convention.
- ``NewDefaultHistogram`` helper.
- ``Registry.Handler`` and ``Registry.YieldExporter`` deprecation.
- Cleanup of legacy import paths.
- Updating examples to use acknowledged patterns.
- Parameterizing the random parameter namespaces for ``examples/random/main.go``, which is useful for demoing population behaviors.
- Provide better examples in the examples subdirectory.
- Make the comments consistent in terms of using multi-line format for future-proofing.
- Extract major constants out.
