Installed PinChangeInt library

Copied only the PinChangeInt subdirectory out of version 1.72 (latest
non-beta release) of Pin Change Interrupt library from Google Code site
Amelia's lights working with hardware interrupts but not with pin change interrupt library

No errors, but pin change interrupts don't seem to work at all. Using
the four hardware interrupts of the Micro and the standard Arduino
syntax works, but using the PinChangeInt syntax simply doesn't cause the
ISRs to be triggered.
Switched to beta version of PinChangInt

Replaced the release version with the beta version, but it still doesn't
work
Copied LadyAda's debounce program

I'm going to attempt to use LadyAda's debounce example in conjunction
with my own variation on the delay() function rather than using
interrupts at all.
Bedroom NeoPixels is looking solid

Good responsiveness to six button control. Everything seems to be
working as intended.
