Detailed Description

template<typename CI>
struct columnar::ContainerId::eventContext< CI >

a template to define a mutable version of a given container id

By default all xAOD objects will be held by const references, but some tools expect to have non-const access (usually to call xAOD-only code). This needs a separate mutable container id, and this template allows to define one with a simple using statement.
