Class Description

 CalSmeared

 CalSmeared is the Fast MC version of a cluster (really should be
 inheriting from Event Cluster class).  In addition to minimal cluster
 attributes it also keeps some information on the "perfect" cluster
 from which it is derived.

CalSmeared(SmearTraj& traj, Bool_t hadron, SmearFuzz* pFuzz, TRandom *pRand)

 Usual constructor.  Inputs are
    -- "perfect" particle position, after propagation
    -- hadron/lepton boolean
    -- smearing parameters
    -- random number generator instance

void spewDiag(FILE* ofile)

 More extensive spew for debugging

void spew(FILE* ofile)

 Typical cluster output for a fastMC cluster looks like
        energy energyPhi energyTheta energyR phiRms thetaRms rRms
        0 hits
        1 particle(s)
        xxxxxxxx

 where the quantities in the first line are floating point and
 xxxxxxxx is index (in array of all MC particles) associated with
 generating MC particle.

 The set of all clusters are bracketed by the lines
    yyy Clusters                          [before]   and
    end                                   [after]

     yyy is the number of clusters to follow.

void ToPolar(const Double_t *pRect, Double_t *pPolar)

 Given rectangular coords, compute polar and store in provided 3-vector.
 (theta, phi, r).  The following conventions are used:
 0 <= phi < 2 pi
 0 < phi < pi/2 for x, y > 0.  pi/2 < phi < pi for x < 0, y > 0, etc.
 0 <= theta < pi; theta < pi/2 for z > 0

void Rotate(Double_t* inVec, Double_t* angleVec, Double_t* result) // Rotate something so that z axis is "returned" // to normalVec. That is, if angleVec has polar coords (theta, phi, r), // rotate about y-axis by theta, then about z-axis by phi.

 We need to rotate by theta, phi coordinates of momentum

void RotateTheta(const Double_t theta, Double_t *iVec, Double_t *rVec) // Rotate about y-axis with angle theta

void RotatePhi(const Double_t phi, Double_t *iVec, Double_t *rVec) // Rotate about z-axis with angle phi
