v0.3.0

Highligths:

• Add preStep optional section in configuration: This section is a template that is evaluated just once in the beginning. A .targets object is injected with the whole list of targets. This object is injected only in this stage to allow filter items on-demand before conditions evaluation. This feature is related to the following point

• Add setVar function to templates to store data during the whole template evaluation lifecycle: Now there is a function setVar that is able to store keys under .vars scope.

• Helpful README: examples for setVar function
