Interface Summary
Interface	Description
Function	Represents a real-valued function $\mathbb{R} \rightarrow \mathbb{R}$ .
ParametrizedFunction	A function parametrized by some real number.

Class Summary
Class	Description
BipolarStep	Implements the bipolar step function.
FastGaussian	Fast implementation of the gaussian function which is defined as: $%resolution{160} $f(x) = e^{\frac{-x^{2}}{2 \cdot \sigma^{2}}}$$ Where $\sigma$ is a constant defined by user.
FastSigmoid	Implements a sigmoid function defined as follows: $f(x) = \frac{1}{1+e^{-\beta \cdot x}}$ Where $\beta$ is a constant defined by user.
FastTanh	Fast implementation of the hyperbolic tangent function, which is defined as follows: $tanh(x) = 1 - \frac{2}{1+e^{2 \cdot x}}$ It calculates approximated value of `exp(x)` function, instead of using standard `Math.exp` method.
Gaussian	Implements the gaussian function defined as: $%resolution{160} $f(x) = e^{\frac{-x^{2}}{2 \cdot \sigma^{2}}}$$ Where $\sigma$ is a constant defined by user.
Identity	Implements the identity function:
Linear	The linear function implementation.
Sigmoid	Implements a sigmoid function defined as follows: $f(x) = \frac{1}{1+e^{-\beta \cdot x}}$ Where $\beta$ is a constant defined by user.
Tanh	Implements the hyperbolic tangent.
