started trying to use Execution for 'run'
get run to work with ExecutionContext
return JobStats from run, move tmpJar config inside
add TODO about the replCodeJar stuff
clean up replCodeJar code
add actual tests of the repl using Execution
fix ReplTutorial1's use of 'run'
fix logging for ReplTest
revert accidental change to scalaVersion
explain 'snapshot' test, use 'must_=='
fix test, 'contain' doesn't work that way for String, use 'beMatching'
Merge pull request #928 from bholt/repl+execution

Use Execution to run flows in REPL
