Create Parachain

Obtain Basic Adder Example by Rob (was in branch rh-simple-parachain) https://github.com/paritytech/polkadot/tree/master/polkadot/parachain/test-chains/basic_add or try fork of the Basic Adder by Adrian (apparently fixes compile errors)

Also try adder-collator in branch rh-simple-parachain (appears to have disappeared...). Run adder-collator binary with arguments to connect it to validators in the network, which also runs the relay chain OR try fork of the Basic Adder by Adrian (apparently fixes compile errors) https://github.com/adrianbrink/polkadot/tree/ab/fix_adder

View Polkadot Node logs until it says Super majority approval Send transaction and query the Parachain Basic Adder (Test) Parachain is too simple for transactions to be executed against it, as it's a minimal test parachain for adding a number. References:
