Commented out some EEPROM code;

Commented out EEPROM code not being used.

Made some minor changes to comments and display messages.

*** Previous code’s corruption of gasVal1 data no longer happening.
Not sure why … until further detailed investigation of code revealed a
buffer overflow problem due to the way the timers are coded and the
number of characters used in some of the display messages.  Will fix
those issues in the next commit. ***
Fixed buffer overflow; reworked timers

Fixed buffer overflow problem that was resulting in corruption of
stored value for gasVal1.

Reworked the timer functionality so that it doesn’t ever store a value
less than 0.

Added some comments to better label code blocks.

*** This code displays a count UP timer, though, and I want it to
display a count DOWN timer. ***
