Robustness of GRMustacheErrorHandlingTest
Test that the boolean value of collection items is ignored when iterating collections
Remove pointless tests from GRMustacheRenderingObjectTest
Introduce optional [GRMustacheRendering mustacheBoolValue] method, which controls whether section tags are rendered or not. Deprecate GRMustacheTagTypeInvertedSection.
Remove pointless use of GRMustacheTagTypeInvertedSection in standard library helpers and NSFormatter
Introduce `zip` filter in the standard library. Tests for features introduced in v7.2
Rendering Object Guide: documentation of the mustacheBoolValue methid
Introduce `each` filter which aims at Handlebars compatibility
`each` renders an error if argument is not iterable. Don’t generate `@last` key any longer, which puts too much constraint on collections.
`each` filter iterate dictionaries
TODO: `each` filter should set the `@last` key just like Handlebars.js does
Write `zip` filter with public APIs
`each` filter now provides the `@last` key
Tests for the `@last` key set by the `each` filter + robustness of `zip` test
