How to use:
White stained glass = wire
Lime stained glass = Voltage Source
Yellow stained glass = current source
Orange stained glass = resistor
Gray stained glass = ground

1) Make closed loop circuit, place ground somewhere.
2) Stand on the glass anywhere and run function ck:create, if it is a valid circuit it will spawn the elements with default values
3) Edit values using /trigger setElem set (value)
where value is 100x desired value. This sets an element within 3 blocks to that value. (eg: 2.75mA = /trigger setElem set 275)
4) Run /function ck:solve near the circuit for it to attempt to solve. Currents, and powers will be displayed for all elements.
*Note: limited number of nodes and sources and does not always work depending on configuration, and will probably say "ERROR Matrix not invertable" if the configuration is not solvable.
