## Route two matched capacitors, C1 and C2, drawn in a capacitor matrix.
#  Connections are put in place with reference to a given matching scheme.
#  Elementary capacitor units are connected to horizontal and vertical routing
#  tracks that represent top plates and bottom plates nets of C1 and C2.
#  Supported types of capacitors are Poly-Poly and Metal-Metal.
#  Technologycal rules are provided by 350 nm AMS CMOS technology with
#  three-four metal layers. Metal layers that are used for routeing are
#  placed similarly to horziontal-vertical (HV) symbolic Alliance CAD tool router,
#  where horizontal metal channels are drawn in metal 2 and the vertical ones are
#  in metal 3. Given a matrix of dimensions \f$ R*C \f$, the total number of
#  vertical tracks is \f$ 2C+2 \f$ equivalent to \f$ C+1 \f$ couples,
#  ensuring that every elementary capacitor is positioned between four
#  vertical tracks, two from each side. In fact, every adjacent couple of these
#  tracks represent top plates and bottom plates of C1 or C2 as shown in Figure 1.
#
#  \image html Layout.png "Layout" width=.1\linewidth
#
#  An elementary capacitor unit can be a part of C1 or C2 according to the
#  matching scheme. However, to respect common-centroid layout specifications,
#  for C1 and C2 to be equal, the matrix number of colums and number of rows
#  must be both even. Addionnally, the number of elementary capacitors dedicated
#  to C1 must be equal to those dedicated to C2. These two conditions are tested
#  in one of the class methods. An exception is raised if at least one of the two
#  is not respected.
