Dear Users,

1. Keywords of SOL, such as DX and DPX, etc., can be used for matching. This is convenient to adjust the geometry such as dCHI1("bending angle") of a MULT with K0 surrounded by SOLs. If a parameter of a SOL is FREEd, numerical derivatives are applied no matter FFS$NumericalDerivative is set.

2. The expression of MULT in a solenoid was updated to a slightly simpler one.

3. Removed some unused dummy arguments in tfsetv, etc.
