initial steps in documenting process & adding guitar.
some notes i've taken along the way.
historical artifact from the overtone group
ignore samples
Simple mods get a ~10x speedup.  (18s -> 1.6s)  Nice.
Hit Issue #222 & 223 on Overtone, bumped up to 0.9.0-SNAPSHOT.  Finally figured out that adding a leak-dc equivalent would allow for better analysis.  Will have to add a leak-dc to the cello synth to avoid some of the crazy areas in the samples.  double-array + ^double type-hints for the perf win--went from "out of heap memory" to almost no cost for the leak-dc.  [some odd perf potholes once in a while, though...]
Add leak-dc to the sample output.  Fixes a few "TOO LOUD!!" issues.
Update to add :cello tests.
Move cello from bank/inst/raw -> bank/inst code split.  Next to add synth & delete raw.
remove cello raw file
Add cello synth + tests.
Add piano synth. Switch to using bank/inst/synth division of files.  remove raw piano file.
Minor tweaks to cello & test.
checkpoint some analysis mods.
Update to note synth/inst variants.  Add note about explicit note-off control.
Oops, forgot piano synth.
Adding dB display function.  Definitely looks like this is a good way to partition samples.  logarithms ftw.
moving some files around
some minor edits
Ugh...need more memory.  Don't need criterium.
