zrrichards: Add function to incrementally change between two colors given a Fraction. Code works but the initial and final colors need to be tweaked
zrrichards: Change progress bars to gradually change from red to green, without passing through brown
zrrichards: Remove printStackTrace in method to check if a string is parseable
zrrichards: Remove erroneous TODO statements
zrrichards: Explicitly set the color to red if zero
zrrichards:  Remove debugging code and add TODO
zrrichards: Dim the green and red so they're not so bright
zrrichards: Changes colors to original red and green, these are duller and thus easier on the eyes and more pleasant to look at
zrrichards: Make getColor method public and static to be used from another class
zrrichards: Enhance main progress bar to change colors. Refactor setValue to use the Fraction class and concatenate the value shown in the progress bar so "33.3" is shown instead of "33.333333333"
