Dynamic Jenkins Job Scheduler

	// Schedule builds TeamCity style: Given a dependency relationship between builds,
	// start all builds whose prerequisite builds have completed.

	// This is intended to be run as a system groovy script in Jenkins.

	// Unbound variables:
	// sleepSeconds - amount of time to sleep between polls. 5-15 seconds seem good.

	// Every entry in the jobToRun map is expected to have this format:
	// JobId: [ JobName: <actual jenkins name of the job>,
