Class <code>std::ana::Particle</code> represents reconstructed particles in detector as well as unstable particle candidates formed via combination of final-state-particles.

The following constructors are implemented:
* Default constructor
<code>
Particle(ThreeVector momentum, float mass, int pdgCode, EParticleType particleType=c_Undefined);
/** All other private members are set to their default values (0). */
Particle(const FourVector& momentum, int pdgCode, EParticleType particleType=c_Undefined);
/** Constructor for composite particles. */
Particle(std::vector<ParticlePtr> daughters, int pdgCode);
/** Constructor from MC Particle of podio tree */
Particle(const sct::MCParticle &mcparticle);
/** Constructor from MC Particle of podio tree */
Particle(const sct::Particle &particle, int pdg, size_t partIndex);
</code>

Getters:
* <code>int pdgCode()</code>
* <code>float charge()</code>
<code>
EFlavorType flavorType() const;
EParticleType particleType() const;
float mass() const;
/** Particle nominal mass */
float pdgMass(void) const;
float energy() const;

/** Returns four-momentum vector [px, py, pz, E] */
FourVector fourMomentum() const;
const ThreeVector& momentum() const;
float momentumMagnitude() const;
/** Returns momentum magnitude (same as getMomentumMagnitude but with shorter name) */
float p() const;
float px() const;
float py() const;
float pz() const;

/** Returns vertex position (POCA for charged, IP for neutral FS particles) */
const ThreeVector& vertex() const;
float x() const;
float y() const;
float z() const;
size_t mdstIndex() const;
</code>

Modificators:
<code>
void set3Momentum(ThreeVector p3);
void set4Momentum(ThreeVector p3, float mass);
inline void set4Momentum(const FourVector &p4);
inline void setVertex(ThreeVector vertex);
/** Sets 7x7 error matrix (order: px,py,pz,E,x,y,z) */
void setMomentumVertexErrorMatrix(ErrMatrix errMatrix);
/** Sets chi^2 probability of fit */
void setPValue(float pValue);
void updateMass(int pdgCode);
void appendDaughter(ParticlePtr daughter);
void removeDaughter(ParticlePtr daughter);
