Remove EnqIO, DeqIO - #308

Generate a better error message for missing IO() wrapper - fix #305

clone firrtlDirection when cloning - Issue #306

Use "chisel3" as sbt project name.

Add Cookbook tests

Update Driver: Check the simulation exit code #281

Merge with master and support checking for failure with an explicit assertion message.

TransitName comment change.

Update @sdtwigg's PR #199 - Add Assert Data.

This was originally mixed in with #199, Add Assert Data.

Update to current sbt resolver idiom.

Give <> and := legacy behavior in compatibility mode

Static accesses are strictly checked.

Make asInput/asOutput/flip deprecation warnings dynamic

Code that imports Chisel._ shouldn't see them.

Not sure if requireIOWrap is the right condition... or if cyan is a
good choice of color for deprecation warnings.

Generate scaladoc for all subprojects.

@unchecked is better than matching on _ in this case, because we want to
fail on an unexpected case, rather than silently proceed.

Gsdt - Fixup to Chisel connections and direction - PR 200 revisited.

Add Data dir method to Chisel compatibility layer.

Massive rename of CompileOptions.

Massage CompileOption names in an attempt to preserve default (Strict) CompileOptions in the absence of explicit imports.
NOTE: Since the default is now strict, we may encounter errors when we generate connections for clients (i.e., in Vec.do_apply() when we wire up a sequence).
We should really thread the CompileOptions through the macro system so the client's implicits are used.

Use aggregate to run project tasks in subprojects
Use sbt-unidoc to generate combined scaladoc for project and subprojects.

Don't use firrtlDirection for direction checks - fix #298.

firrtlDirection should only be used for emitting firrtl. Any checks on the actual direction should use the bound Direction `dir`.
