Updated Scala (2.11.6) and Chisel (3.0) versions.
Add chisel2 Makefile

use delayed init to ensure collectelts and further improve walk bundle and changed getDeclaredMethods to getMethods for inheritance but still gets constructor param

This probably breaks some stuff.

Necessary for backwards compatibility.

But they aren't actually implemented yet.

These avoid the implicit conversion to BigInt for e.g. (foo << 10).

- Remove redundant operator emission code
- Specify types explicitly on public methods
- Add missing Bool operators
- Remove constant folding (this should happen in the backend)

rename id to cid, legalizeNames, better flo/dbl support in tester, better mux handling and check for uint/sint, support for bulk connect, filter ? as well
