Linear Damper (Damper)
Linear mechanical damping (i.e. opposing force proportional to the velocity). In Laplace domain with \(s\in\mathbb C\):
\begin{equation*}
e(s) = A \, f(s).
\end{equation*}

Example
>>> # Import dictionary
>>> from pyphs.dictionary import mechanics_dual
>>> # Define component label
>>> label = 'damp'
>>> # Define component nodes
>>> nodes = ('N1', 'N2')
>>> # Define component parameters
>>> parameters = {'A': 1.0, # Damping coefficient (N.s/m)
... }
>>> # Instanciate component
>>> component = mechanics_dual.Damper(label, nodes, **parameters)
>>> # Graph dimensions
>>> len(component.nodes)
2
>>> len(component.edges)
