Returns the hadron beam spin vector in the current frame.
If the spin vector in the rest frame of the hadron (of mass m) is n and the 4-momentum of the hadron in the current frame is p = (E,P), then the hadron spin 4-vector in the current frame is (Bjorken & Drell, 1965):
s = (s0, S)
where
s0 = n.P / m S = n + (E/m - 1)(P.n) P / |P|^2

Set the event properties from a string.
The string format should be as follows:
quark, x, Q2, nu, y, W2, z, hadronPt, leptonTheta, leptonPhi, phiSpin, phiHadron, f1, g1, h1, D1, f1Tperp, f1Tperp1, f1Tperp12 H1perp, H1perp1, H1perp12, AUT_Siv, AUT_WtSiv, AUT_Siv_allq, AUT_WtSiv_allq, AUT_Siv_piDiff, AUT_WtSiv_piDiff, AUT_Col, AUT_WtCol, AUT_Col_allq, AUT_WtCol_allq, AUT_Tw3_Col, AUT_WtTw3_Col, X_UU, X_SIV, X_COL
Returns true if the string is processed successfully, false if not.
