App Shows Superheroes With DiSC Profiles Most and Least Like The Selected Hero
Graph Caliper Attributes
Merge branch 'add-graphing-of-caliper-data' into leastlike-tooltips

Conflicts:
	app/templates/superheroes/show.hbs
only consider heroes with an attribute difference of > 40 for dissimilar

rigged the 'sociability' attribute so that only four heroes are >40 off
from Alaina's sociability (for testing)
implemented KSD's "dissimilar must be > 40" for dissimilar attributes

moved similarityMatrix from show.js controller to superhero.js model

use Case.title() to capitalize attribute names in attribute-tooltip.js

eliminated capitalized attribute names in show.hbs

for testing: changed fixtures so that all heroes have 93 assertiveness, and
  only 4 heroes have non-middle sociability
