Coarse-grained confidence level of how well a particular finding
satisfies the criteria to match a particular infoType.
Likelihood is calculated based on the number of signals a finding
has that implies that the finding matches the infoType. For example,
a string that has an '@' and a '.com' is more likely to be a match
for an email address than a string that only has an '@'.
In general, the highest likelihood level has the strongest signals
that indicate a match. That is, a finding with a high likelihood has
a low chance of being a false positive.
