 * @file makeGlobalHistoConfigObject.C
 * @brief Creation of Global Histo component configuration objects in OCDB
 *
 * <pre>
 * Usage:
 *  aliroot -b -q makeGlobalHistoConfigObject.C'("path", "key", "uri", runmin, runmax)'
 * </pre>
 *
 * Create an OCDB entry with a TObjString containing param.
 * Many HLT components understand configuration strings containing
 * arguments and parameters just like the command line arguments.
 * This macro facilitates the creation of an appropriate object
 * from a parameter string.
 * As another approach the TObjString parameters are stored in a TMap
 * associated to a key. A TMap object is generated if 'key' is specified.
 *
 * Parameters: <br>
 * - path           path of the entry within the OCDB (e.g. HLT/ConfigHLT/GlobalHisto)
 * - uri   (opt)    the OCDB URI, default $ALICE_ROOT/OCDB   
 * - runmin (opt)   default 0
 * - runmax (opt)   default 999999999
 * The parameters of the component configuration should be defined inside function makeString().
 *
 * Note: The configuration procedure of an HLT component is not
 * restricted to that scheme. The implementation is up to the
 * developer and more complex objects are possible.
