Functions
TString	RegionCutStore::Dir ()
	Directory holding the region cut files.
TString	RegionCutStore::Path (const char *name, Int_t reac)
	Path to one cut's file.
void	RegionCutStore::Save (Int_t reac, TCutG *cut_an, TCutG *cut_aa, Double_t n_an_assigned=-1.0)
	Write a strip's two region cuts.
TCutG *	RegionCutStore::Load (const char *name, Int_t reac)
	Load a cut, from either storage generation.
TCutG *	RegionCutStore::LoadDrawn (const char *name, Int_t reac)
	Load only a hand-drawn cut, never a fitted one.
Double_t	RegionCutStore::LoadAssigned (const char *name, Int_t reac)
	The attributed count stored with a cut.
void	RegionCutStore::SaveFit (Int_t reac, const RegionFit &fit)
	Store the fitted components beside the (a,n) cut.
Bool_t	RegionCutStore::LoadFit (Int_t reac, RegionFit &fit)
	Read back a stored fit.
RegionFit	RegionCutFinder::FitMixture (TH2F *scatter, Int_t reac, Double_t x_lo, Double_t x_hi, Double_t y_lo, Double_t y_hi)

RegionFit	RegionCutFinder::FitBeam (TH2F *scatter, Int_t reac, Double_t x_lo, Double_t x_hi, Double_t y_lo, Double_t y_hi)
	Fit the beam component alone, with no reaction component.
Double_t	RegionCutFinder::AboveRidge (const Gauss2D &beam, Double_t x, Double_t y)
	How far a point sits above the beam ridge, in conditional sigma.
TCutG *	RegionCutFinder::RidgeBandCut (const char *name, const Gauss2D &beam, Double_t nsig_lo, Double_t nsig_hi, Double_t x_lo, Double_t x_hi, Double_t y_lo, Double_t y_hi)
	Closed polygon of a band above the beam ridge.
Double_t	RegionCutFinder::CountInside (TH2F *scatter, TCutG *cut, const RegionFit &fit)
	Count scatter events inside a cut.
void	RegionCutFinder::SaveFigures (TH2F *scatter, Int_t reac, const RegionFit &fit, TCutG *an, TCutG *aa, const TString &subdir)
	Save the diagnostic figures for a strip's regions.
