Parallel DCuhre Output

Calling quad::Cuhre's "integrate" method, returns an object of type cuhreResult.

CuhreResult members:

• double estimate: the estimate of the integral's true value
• double errorest: the estimated error of the estimate
• size_t neval: the number of function evaluations performed
• size_t nregions: the number of regions processed (this is not the number of regions in the last iteration of the sub-region tree)
• int status: Flag for integrator's termination (0 = converge, 1 = not reached sufficiently small errorest, 2 = converged in Phase 1)
• int lastPhase: the last phase the integrator had to execute
• size_t phase2_failedblocks: for debugging purposes only, displays the number of phase 1 regions, that needed further sub-division in Phase 2
