Generating CDDL instances

First you need to install cddl

sudo apt install ruby
sudo gem install cddl
sudo gem install cbor-diag

You can generate new tests with

1. cddl specs/shelley.cddl generate 1 > test/name_here.diag
2. diag2cbor.rb test/name_here.diag > test/name_here.cbor

You can combine these together with cddl specs/shelley.cddl generate 1 | diag2cbor.rb > test/name_here.cbor
