considering revising control flow. See PeckolNotes.txt
measurements queued, but never read. Next step: reorder control structure
begin to change control flow
Measure and compute tasks part of new ctrl flow
ekg tasks integrated into control flow

many sections of code commented out to allow running w/o errors. The majority
of the sections are being rewritten to fix bugs any ways. BUT remember to
revisit & uncomment code from measure, compute, ekgCapture, ekgProcess. Also
remove the variaous debug printlns.
