aliased #special as #prerelease and #special= as #prerelease=
failing spec for comparison of prereleases
semvers compare prerelease against non-prerelease
version with prerelease compares to less than an equal version without prerelease
more verbose comparison test to ensure i don't break anything
fixed comments on #prerelease and #prerelease=
correctly compares semvers according to prerelease
failing specs for semver metadata
fixed bug in #prerelease? method
FINALLY nailed that stupid parsing bug! metadata is now properly parsed from the version string.
removed comment message about unexpected behavior now
semver saves and loads metadata, returns empty metadata for ancestral semver files
extracted pre-release comparison into separate PreRelease class that implements Comparable
added 'James Childress' to contributors list and bumped minor version
Merge pull request #2 from jameschildress/meta
