def _getReportItem(itemName, results):
subKeys = itemName.split('<STR_LIT::>')<EOL>subResults = results<EOL>for subKey in subKeys:<EOL><INDENT>subResults = subResults[subKey]<EOL><DEDENT>return subResults<EOL>
Get a specific item by name out of the results dict.

The format of itemName is a string of dictionary keys separated by colons,
each key being one level deeper into the results dict. For example,
'key1:key2' would fetch results['key1']['key2'].

If itemName is not found in results, then None is returned
