nested to nestedConfig
Added the basis for timeout, now need to write tests. Moved out test heleprs into a util file
started first test for timeout, renamed expectError to completeWithError as that is more what it was for
renamed util
fixed abstractions of util
tests now use delay var
new nested timeout test is failing, not sure why
added nestedTaskConfig
Added onError: 'ignore' support for tasks. Currently only occurs for double callback errors
Fixed nested task config on suites
