FixedPoint number support for chisel3 (#328)
* FixedPoint number support for chisel3
FixedPoint numbers have a width and a binary position
Either, neither or both maybe inferred.
Firrtl will convert these to SInts during lowering passes
* Fixes based on Jack's comments on PR #328
* Add experimental warning to FixedPoint class and object
* Fixed comment per Adam's comment on PR #328
