Represents the data of a build of a build server.
A TeamCityBuild may be derived from a TeamCity build log. Besides information about the build (like the name of the project, the build number, and the status) a TeamCity build log holds information about every build step. Every line of a build log may be stored as a TeamCityBuildLogEntry both directly as a log entry of the TeamCityBuild but also as a log entry of a TeamCityBuildStep. However lines not belonging to a certain build step are only stored once.
