Detailed Description

Used to set which EventSetup provider should provide a particular data item
in the case where multiple providers are capable of delivering the data.
The first argument specifies the C++ class type of the prodiver.
If the provider has been given a label, you must specify that label as the second argument.
Additional 'vstring' arguments maybe used to specify exactly which EventSetup Records
are being preferred and optionally which data items within that Record.
E.g.,
    #prefer all data in record 'OrangeRecord' from 'juicer'
    ESPrefer("ESJuicerProd", OrangeRecord=cms.vstring())
or
    #prefer only "Orange" data in "OrangeRecord" from "juicer" 
    ESPrefer("ESJuicerProd", OrangeRecord=cms.vstring("ExtraPulp"))
or 
    #prefer only "Orange" data with label "ExtraPulp" in "OrangeRecord" from "juicer" 
    ESPrefer("ESJuicerProd", OrangeRecord=cms.vstring("Orange/ExtraPulp"))
