Detailed Description

OH histogram lock header file.

Provides a mutex to lock histogram operations to avoid OH publication while certain operations (e.g. re-binning) are ongoing. This is only relevant for online operations and only has any effect once oh_lock_histogram_mutex::set_histogram_mutex has been called to set a reference to the global OH mutex in tdaq: https://gitlab.cern.ch/atlas-tdaq-software/oh/blob/master/oh/OHRootMutex.h.
