Data Containers

Many of the basic data classes - again hits and tracks are good examples - are usually stored in so-called container classes, with TPhObjectContainer for unnamed objects and TPhHashList for named objects being the most common ones. The container classes provide common I/O for all objects stored in them and allow a large collection of objects to be passed around between different analysis modules, usually by storing and retrieving from either the TPhEvent object or the TPhObjectManager object.
The data containers are named objects, allowing a storage of an arbitrary number of containers in the event or object manager, provided they are identified by a unique name.
