In order to add more filter topologies to qucs-filter tool, quarter\wave
structures for bandpass and notch masks were included. Since TL_filter class
provides microstrip line synthesis, microstrip quarter wave filters were also
implemented. Given the desired filter parameters, the quarterwave_filter class
calculates the impedance/width and length of the transmission lines using [1].
qucs-filter.cpp was also modified to call quarter_wave_filter class.
On the other hand, the basic design equations of the filter were added to the
technical documentation "qucs-doc/technical/synthesis.tex"
