BuiltIterable is now available for when you want to accept a BuiltList or a BuiltSet.

Use real generic syntax

Merge pull request #99 from davidmorgan/generics-syntax

Use real generic syntax.

Add operator[] to ListBuilder and MapBuilder

This makes it possible to do inline updates like

  list = list.rebuild((b) => b[0]++);
  map = map.rebuild((b) => b['key']++);

Minor change to BuiltSet

Widen parameter of BuiltSet.difference and BuiltSet.intersection to BuiltSet to match Set.

Add asList, asSet, asMap methods

Also update for compatibility with SDK 1.21.0 which changes the Set.difference method.

Relax type checks based on strong mode guarantees

From 1.1.0, please make sure code using built_collection passes strong mode checks:

https://github.com/dart-lang/dev_compiler/blob/master/STRONG_MODE.md

For example, this used to need a runtime check:

new BuiltList((b) => b..add('not an int'))

Now it can be caught via static analysis, so the runtime check has been removed to improve performance.
