* A group of log statements related to each other.

* A LogUnit is collection of LogStatements, each of which is generated by at a particular point
* in the code. (There is no LogStatement class; the data is stored across the instance variables
* here.) A single LogUnit's statements can correspond to all the calls made while in the same
* composing region, or all the calls between committing the last composing region, and the first
* character of the next composing region.
*
* Individual statements in a log may be marked as potentially private. If so, then they are only
* published to a ResearchLog if the ResearchLogger determines that publishing the entire LogUnit
* will not violate the user's privacy. Checks for this may include whether other LogUnits have
* been published recently, or whether the LogUnit contains numbers, etc.
