Conflicts:

Removed xml2js function since it does not work - assumes DOM object as input and there is no easy way of adding that functionality.
Changes in JavaScript:
- `recordSet.map` now creates and returns a new array from returns of callback 
- `recordSet.each` calls callback on each element and returns recordSet (function of `map` before the change)
