Functions
std::int64_t	LatticeTester::lFactorial (int64_t t)
	Calculates \(t!\), the factorial of \(t\).
double	LatticeTester::Digamma (double x)
	Returns the value of the logarithmic derivative of the Gamma function \(\psi(x) = \Gamma'(x) / \Gamma(x)\).
double	LatticeTester::BernoulliPoly (int64_t n, double x)
	Evaluates the Bernoulli polynomial \(B_n(x)\) of degree \(n\) at \(x\).
double	LatticeTester::Harmonic (std::int64_t n)
	Computes the \(n\)-th harmonic number \(H_n = \sum_{j=1}^n 1/j\).
double	LatticeTester::Harmonic2 (std::int64_t n)
	Computes the sum.
double	LatticeTester::FourierC1 (double x, std::int64_t n)
	Computes and returns the value of the series (see [5])
double	LatticeTester::FourierE1 (double x, std::int64_t n)
	Computes and returns the value of the series.
