Major Browser Compatibility Fixed

So far this has been tested and working on the most common modern browsers.

support delete for localStorage trap

expl.: delete lsState.a;
will remove the prop a on object, if existing, and at localStorage

"for in"-loop support for LocalStorage trap

The LocalStorage trap does mock setting props to localStorage instead to set it to the object. Looping now allows to also read those props from localStorage without defining the prop name.

Code fixed by Standard

Introduced standard (https://github.com/standard/standard) linting and added some little minor updates to the css trap.

Namings

This aligns Subscribe (former Join) naming with observable libraries.

Initial Release

First release with 10 basic traps.
