IBM Blockchain Platform notes

Starter plan

Trying to get starter plan to work using the Composer playgound...

Eventually found this bit of doc which seems like a start: https://console.bluemix.net/docs/services/blockchain/develop_starter.html#deploying-a-business-network
Viewing the raw JSON and creating a business network card in the playground should work
Fail! Going to need to actually follow the very long instructions and use the cli to create a card! (Just give me a button!)

Hackety hack to publish jars to a directory inside a Hyperledger Fabric smart contract

	/*
	* This gradle init script can be used to publish jars to a repository folder
	* inside a Fabric contract project. For example, in the `fabric-chaincode-java` project:
	*
	* ./gradlew -I ~/chaincode-init.gradle -PchaincodeRepoDir=<chaincode_dir>/repository publishShimJarPublicationToFabricRepository publishProtosJarPublicationToFabricRepository
	*
	* Where <chaincode_dir> is the chaincode location containing your contract!
	*
	* Fabric contract projects can then use jars from the bundled maven repository
	* during the Fabric instantiation process by adding the following repository
