Used only when the EXACT flag is set for TWISS Probably not complete for a nonzero XTILT (undocumented parameter)
No attempt to make xtilt exact; would be possible with some refactoring
Updated original test-thick-solenoid test with new results Note original time calculation for the thick case was particularly bad Updated test-twiss-17

For
twiss, uses theexactflag totwissto choose between the original algorithm and the exact calculation. Switchtrackto using the exact calculation. Fortrack, the original time of flight computation is significantly improved for the case intest-thick-solenoid(compare the thin and thick results).twissdoes everything through second order. Created a new test case comparing toptc_twissresults. Radiation calculations should be nearly unchanged (only differences should be related to using the exactly computed longitudinal momentum), I did not attempt to add radiation in the solenoid body.
