Detailed Description

Incrementally define and initialize a PVStructure

Equivalent to FieldBuilder with the added ability to assign initial values.

epics::pvData::PVStructurePtr val(epics::pvData::ValueBuilder()
                                  .add<pvInt>("intfld", 42)
                                  .addNested("sub")
                                   .add<pvString>("strfld", "testing")
                                  .endNested()
                                  .buildPVStructure());
