  * Interface that defines a skeleton for default function, unit and variable
  * handling. Its use is deprecated because it is less performant than using the
  * UnitCB, FunctionCB or VariableCB adaptor classes. The reason is that the latter
  * ones are resolved at compile time (creation of the Expression) while the former
  * one is resolved each time at evaluation of a unit, function of variable.

  * @deprecated use the more performant UnitCB, VariableCB and FunctionCB in stead
