refactor(parser): better jsdoc, some behavior fixes, more tests

— all operations on nodes moved to `createList` function
- fixed problem with single tags with value only like `[url=value]` fixes #6
- write tests for `Token` class
- moved all node arrays to parse func, now parser supports many instances
- add jsdoc to critical parts of the parser to better understanding how it works
