/*
    This method is used to store the hashes of Reference header values in a custom field
    This allows association of issues (to drive commenting) based on the reference header only.
    
    cfID      - The ID of the custom field used (i.e. "customfield_12345")
    cfName    - The name of the Custom field (i.e. "Reference Hash")
    timeFrame - Only issues updated in the timeframe will be associated to. e.g. ("-24h")
    (h- hours, d- days, w- weeks, etc..)
