Create a simple system for executions and command line parameters (#337)

Create a simple system for executions and command line parameters
New model for tracking parameters and having those parameters
register scopt command to allow the parameters to be set by
command line args.

Create composable forms of the these parameters to allow separate
elements of the chisel3 toolchain to combine these parameters
Create execution return structures that simplify return values
to earlier toolchain elements
