Relax native implementation detection, stringification of instance should returm expected result (not necesarily prototype)
Add "ponyfill" keyword to meta description. Fixes #7
Fix isNativeImplemented, so it's not affected by #3619 V8 bug
It's v0.1.3 republished as v1.0.0
Republish v0.1.2 as v0.1.4 due to breaking changes (v0.1.3 should have been published as next major)
Update up to changes in specification (require new, remove clear method)
Use internal random and unique id generator instead of external (time-uuid based). Global uniqueness is not needed in scope of this module. Fixes #1
Improve valid WeakMap detection
Assure to depend only npm hosted dependencies
