//OPM calls this function for each property to obtain a list of strings and cookies if they are available.
//For our textstyle property we would like to display all the textstyles currently available in the database.
//This function is declared on the IPerPropertyBrowsing interface. Our IOPMPropertyExtensionImpl
//class implements this member by reading the values in the OPM property map. (You set this up in your
//head file when you use BEGIN_OPMPROP_MAP, OPMPROP_ENTRY, END_OPMPROP_MAP macros.)
//Since we need a dynamic list of entries in this drop down list and a static map cannot implement this,
//we need to override this function a provide dynamic list of text styles to OPM.
