Plot TARP expected coverage

Draws the expected coverage probability (ECP) curve from tarp() against the nominal credibility level. A calibrated posterior lies on the diagonal; a curve above the diagonal means the posterior is too wide (conservative), below means overconfident. The shaded band shows the Monte-Carlo uncertainty from the finite number of TARP trials.
