 * Hardware description languages
   Hardware description languages, HDLs for short, are used to model circuits, typically digital.
   HDLs are *declarative* languages, they describe how the circuit should be constructed.

   Instead of describing how text should be rendered HDLs describe how wires and components in a 
   circuit should be connected.
   Although we have yet to introduce chisel, let's look at some code for a chisel circuit:

 ** Scala -> Chisel Graph Builder
    The starting point, a scala program describing how to build a chisel graph.
    This program is not constrained in any way, it's able to do anything any other scala program does,
