# Save/restore various lists of algorithms in AIA implementation to/from

# other files. Aim is to easily create a version of AIA that is less

# bloated, for development purposes. Eg, you can save the complete list

# of algorithms, create a version that has just a couple of algorithms

# you might be working on, develop them, then restore the original

# algorithm list. Maybe it will make the system a bit less of a beast

# and easier to run on ancient machines such as mine...

# Currently seems to need heapsort (default alg) and union find

# explanation (due to import somewhere?)

# eslint causes some problems because it seems to look at all the .js

# files, not just the ones used - best use -no-verify in commits etc
