Preparing the schematic capture for ngspice

Some details have to be taken care of preparing for simulation. Here are some of the problems that appeared, and some warnings.

- Don't leave any open connections. Spice doesn't know what to do with them. This includes the output of a circuit - if necessary, connect a large resistor to ground.

- Don't leave two capacitors in series, with nothing else connected to the junction. Spice won't know how to calculate the DC level between them, and won't be able to 'converge'.

- Name important connections (nets) with easy-to-remember names, such as 'in', 'out', etc. (to name a connection, select it, and add an attribute called netname. This netname will be available in Spice too, instead of cryptical numbers.
