[x] Extra line of Headers (5 of them) get printed after the Critical path costs, but before the Average per-process costs
[x] We need to separate output by 3 tabs, not 1, as its hard to follow the columns
[x] We should only have 5 Headers per section, so we need to separate them out. For the critter-routine-specific output, we need to separate into 2 sections: 5 critical path costs, and 5 average per-process costs.
[x] Change "Estimated" to "Est" in Headers to save room
[x] Change "Communication" to "Comm" in Headers to save room
[x] Change "Computation" to "Comp" in Headers to save room
[x] Change "OverlapPotentialTime" to "OverlapTime"
[x] Verify that average metrics are being calculated correctly. It looks too large.
Add more if necessary.
