CalculateRandomShare ( Zp myShare, IList polyUpdate ) : Zp	The i-th user gets a Qj(i) List from users, each user j calculated Qj(i) - the j element in the List
CheckSharedSecrets ( Zp secret, int numberOfPlayers, int polynomDeg, int prime ) : bool
DetailedShare ( Zp secret, int numPlayers, int polynomDeg ) : ShareDetails	Evaluates the shared secrets of secret with polynom of degree t and numberOfPlayers players.
GetRandomizedShares ( int numPlayers, int polynomDeg, int prime ) : IList	Creates a random poynomial Qj(x), for the j player, and creates a list of elements, such that the i-th element is Qj(i)
GetRandomizedSharesByzantineCase ( int numPlayers, int polynomDeg, int prime ) : IList	Creates a random poynomial Qj(x) ,for the j player,and creates a list of elements, such that the i-th element is Qj(i)

Recombine ( IList sharedSecrets, int polynomDeg, int prime ) : Zp
Recombine ( IList sharedSecrets, int polyDeg, int prime, bool usePrimitiveRecombine ) : Zp	Recombines (interpolate) the secret from secret shares.
Share ( Zp secret, int numPlayers, int polyDeg ) : IList	Calculates the shares of a secret with polynomial of degree t and numPlayers players.
Share ( Zp secret, int numPlayers, int polyDeg, IList &coeffs ) : IList	Calculates the shares of a secret with polynomial of degree t and numPlayers players. The method also returns the array of coefficients of the polynomial.
