Functions
template<class T_Parent, class T_Cont, class T>
void	IDTPM::createDecoratorKeysAndAccessor (T_Parent &parent, const SG::ReadHandleKey< T_Cont > &container_key, const std::string &prefix, const std::vector< std::string > &decor_names, std::vector< WriteKeyAccessorPair< T_Cont, T > > &decor_out)
	create a pair composed of a WriteDecorHandleKey to create a decorator handle and an accessor to check the availablilty of a decoration
template<class T_Parent, class T_Cont>
void	IDTPM::createDecoratorKeys (T_Parent &parent, const SG::ReadHandleKey< T_Cont > &container_key, const std::string &prefix, const std::vector< std::string > &decor_names, std::vector< SG::WriteDecorHandleKey< T_Cont > > &decor_out)
	like createDecoratorKeysAndAccessor but without the accessor to check the availablilty of a decoration
template<class T_Cont, class T>
bool	IDTPM::decorationsAllExist (const T_Cont &container, const std::vector< WriteKeyAccessorPair< T_Cont, T > > &keys, bool verbose=false)
	Like above - FIXME: maybe not needed.
template<class T_Cont, class T>
std::vector< OptionalDecoration< T_Cont, T > >	IDTPM::createDecoratorsIfNeeded (const T_Cont &container, const std::vector< WriteKeyAccessorPair< T_Cont, T > > &keys, const EventContext &ctx, bool verbose=false)
	create/book the decorations if they do not exist already
template<class T_Cont, class T>
std::vector< SG::WriteDecorHandle< T_Cont, T > >	IDTPM::createDecorators (const std::vector< SG::WriteDecorHandleKey< T_Cont > > &keys, const EventContext &ctx)
	similar to createDecoratorsIfNeeded, but without the checking if decorations already exist
template<class T_Cont, class T_Cont_Elm, class T>
void	IDTPM::decorateOrWarnIfUnequal (const T_Cont_Elm &particle, WriteAccessorRefPair< T_Cont, T > &decorator, const T &value)
	Fill the decoration if it deas not exist or it has a different value.
template<class T_Cont, class T_Cont_Elm, class T>
void	IDTPM::decorateOrRejectQuietly (const T_Cont_Elm &particle, OptionalDecoration< T_Cont, T > &decorator, const T &value)
	Safe method to fill the decoration if decor flag is true.
template<class T_Cont, class T_Cont_Elm, class T>
void	IDTPM::decorate (const T_Cont_Elm &particle, OptionalDecoration< T_Cont, T > &decorator, const T &value)
	unsafe fill decoration method for convenience
