What commands can be used with this library, or is it just loadValue? Would it 
be possible to turn off all segments with a command, rather than having a "0" 
displayed by using loadValue(0)?

Hi, 
I have not worked on this lib for years ;-)

Only loadValue() is available. The library implements zero leading blanking 
except the 10^0 digit (or first digit). If you want to power down all the 
digits to save power or something then rather remove power from the digits by 
using another NPN transistor on the tails of the four digit transistors toggled 
by another pin on the arduino. So by calling powerDown() (or something) resets 
the arduino pin LOW which deactivates the transistor.
