* make root zone id to be 1 ([605e213](https://github.com/angular/zone.js/commit/605e213))
### BREAKING CHANGES
* New child zones are now created only from a async task
that installed a custom zone.
Previously even without a custom zone installed (e.g.
LongStacktracesZone), we would spawn new
child zones for all asynchronous events. This is undesirable and
generally not useful.
It does not make sense for us to create new zones for callbacks from the
root zone since we care
only about callbacks from installed custom zones. This reduces the
overhead of zones.
This primarily means that LongStackTraces zone won't be able to trace
events back to Zone.init(),
but instead the starting point will be the installation of the
LongStacktracesZone. In all practical
situations this should be sufficient.
* zone.js as well as *-zone.js files are moved from / to dist/
* **zone.js:** don't make function declaration in block scope ([229fd8f](https://github.com/angular/zone.js/commit/229fd8f)), closes [#53](https://github.com/angular/zone.js/issues/53) [#54](https://github.com/angular/zone.js/issues/54)
* **lstz:** allow getLongStacktrace to be called with zero args ([26a4dc2](https://github.com/angular/zone.js/commit/26a4dc2)), closes [#47](https://github.com/angular/zone.js/issues/47)
* **Zone:** add unique id to each zone ([fb338b6](https://github.com/angular/zone.js/commit/fb338b6)), closes [#45](https://github.com/angular/zone.js/issues/45)
* **patchViaPropertyDescriptor:** disable if properties are not configurable ([fb5e644](https://github.com/angular/zone.js/commit/fb5e644)), closes [#42](https://github.com/angular/zone.js/issues/42)
