# This is the one true way to create a Version.
#
# This method means you can avoid the paradox of versions being invalid without
# designs, and not being able to add designs without a saved version. Also this
# method inserts designs in bulk, rather than one by one.
#
# Before calling this method, callers must guard against concurrent
# modification by obtaining the lock on the design repository. See:
# `DesignManagement::Version.with_lock`.
#
# Parameters:
# - design_actions [DesignManagement::DesignAction]:
# the actions that have been performed in the repository.
# - sha [String]:
# the SHA of the commit that performed them
# - author [User]:
# the user who performed the commit
# returns [DesignManagement::Version]
