Power-factor correction API

Computes the capacitor kVAR needed to raise power factor from current to target at a real load, and optionally the capacitance for a given voltage/frequency. Answers 'How many kVAR of capacitors do I need to correct power factor to 0.95?', 'What capacitor size fixes my PF?'.
