Tau builder

See issue #329

Charm hadron builders (shared with muonic lines)

builder		in Moore	responsible
D0ToKPi		Yes	Coordinators, Alessandra
DpToKPiPi		Yes	Coordinators, Alessandra
DsToKKPi		Yes	Coordinators, Alessandra

JPsiToMuMu		Yes	Donal

For modes such as D** -> D*{+/0} X, Ds* -> Ds gamma, Lc* -> Lc X, we can use selective persistence to keep charged tracks and neutrals close to the built charm hadron. That way, we don't need dedicated D**, Ds*, or Lc* builders.
