Fake datastore: more data to include config
Refactored histograms updates
num_config was already updated during check
Revert "num_config was already updated during check"

This reverts commit ff3ef4d746518b0c2a942738552e9636b6c739d8.

Ouch.  Num_config was intentionally updated late to make sure that only
*new* configs were recorded in the public database.
BUGFIX: fix processing configs

During the check, the number of events can be safely recorded in the
summary.  Not so for the number of configs.  The previous number is used
to determine which configs are new during the update.
Added the ESD directory
Updated some comments
PEP 8
Added scaffolding for generating event ESD
Use ESD for histograms!
Different way of getting path/filename from date
Begin for storage handling functions for ESD storage

Its kinda of messy, sorry...
Don't need temporary directory, use tempfile module
ESD code now runs, does nothing
ESD paths are created on demand
Get ESD destination path
