Work out power solution #2

Whole modular system needs to be powered somehow. Current best solution that we found is to use off the shelf line AC transformers with rectification and regulation on Master board. Check if transformers of such type are easily available. Also, currently, we have decided on bus power to be regulated +/-12V as well as direct connection to the transformer for AC (this would allow to use transformers in modules to create arbitrary voltage). Every other voltage will be derived on module. Decide whether this is the best course off action (maybe add other voltage lines, such as 5V and 3V3?)

It was decided to provide +/-15V and 5V from external supply. Additional voltages will need to be handled by appropriate modules
