Simple example of a "softlock" concurrent database

	let softlock = require('softlock');
	softlock.backoffAlgorithm('linear');
	softlock.maxResets(4);
	let query = softlock.query();

	// Softlock is a concurrent database that emulates a locking mechanism using versioned keys.
	// If a 'locked' key has been changed since the transaction started, then the transaction
	// is rejected and the logic retried

	query.lock(['a','b','c']); // these keys are locked, but their values are not retrieved.
