// by running that build, which is the difference between the total scores for
// all commits on a given builder before and after the build candidate would
// run. Scoring for an individual commit/builder pair is as follows:
//
// -1.0    if no build has ever included this commit on this builder.
// 1.0     if this builder has built AT this commit.
// 1.0 / N if a build on this builer has included this commit, where N is the
//         number of commits included in the build.

// The scoring works out such that build candidates which include commits which
// have never been included in a build have a value-add of >= 2, and other build
// candidates (eg. backfilling) have a value-add of < 2.
//
// Additionally, the scores include a time factor which serves to prioritize
// backfilling of more recent commits. The time factor is an exponential decay
// which is controlled by the timeDecay24Hr parameter. This parameter indicates
// what the time factor should be after 24 hours. For example, setting
// timeDecay24Hr equal to 0.5 causes the score for a build candidate with value
// 1.0 to be 0.5 if the commit is 24 hours old. At 48 hours with a value of 1.0
