class	RunHitFit
	Template class of experiment-independent interface to HitFit. This class is intended to be used inside the programming environment of a specific experiment, where each type of physics objects has its own class/type. For using HitFit with generic four-vector classes, user can't use this class and have to use the Top_Fit class directly. The reason is: this class is designed assuming electron and muon are represented by different object type, a situation which is guaranteed to happen in any experiments. The class contains some static integer constants to limit the maximum amount of jets in an event before fitting. See the description of those constants for details.

std::auto_ptr<Constraint_Intermed> hitfit::make_constraint_intermed ( std::string s )

Helper function to parse input string s and construct the appropriate Constraint_Intermed instance. Returns null if the input string cannot be interpreted as a mass constraint.

The string should be either a numeric constant like

80.4

or a list of integers in parenthesis like

(1 2 4)

Leading spaces are ignored, as is text in a leading <> construction.

Parameters

s	The string to parse which contains information about the mass constraint.

Return:: Valid pointer to the appropriate type of constraint object, i.e. a Constraint_Intermed_Constant or a Constraint_Intermed_Labels.
NULL pointer if the input string cannot be interpreted as a mass constraint.
