The first bugfix for 1.6.x is here...
- Fix resource leak - a reader returned from TemplateLocator.locate() must bee closed right after the template source is read (#36)
- Fix execution of multiple extend segments in one template - defining sections of the same name collide
- IterationMeta - add isOdd() and isEven()
- HelpersBuilder - add more extra helpers (isEqual, isNotEqual, isNull, isNotNull)
