NOTE: getting the value using the customfield id is not the best practice when
writing SIL scripts. See theWorking with Custom Fieldsexample for more
information on the best practices.

NOTE: These scripts assumes that they are running in the context of an issue. Like in a
workflow script or listener for example. If you would like to test these scripts
from the SIL Manager, add an issue key to test with under the Run Configuration
setting (Run > Run Configuration > Context).
