new script to globally switch from "audio frames" to "audio samples" To be run at some point in the near future after various PRs and development branches have been merged into master.

#!/bin/sh
# This script edits the Ardour source code to change all references to "audio frames" into "audio samples". We skip 3rd party and special libraries,
# and after the global edit do a bunch of per-file fixups for things that the global edit can't take care of.
#
# This was written so that it can be run after merging various PRs and development branches in the near term (July 2017) future.
#
# It also reveals just how confusing this naming "scheme" was.

# Three sets of transformations:
# The first changes all instances of "frames" etc. that need to remain in place. They get temporarily converted to FROOME.
# Then we do the global frame->sample substitution.
# Then we change FROOME back to frame etc.
