In DBpower: Finite Sample Power Calculations for Detection Boundary Tests

Apply this function over 1:J to calculate each portion of the integral we need for the upper bound.

1	performIntegralUpper1(j, muVec, sigMat, lBounds1, uBounds1, lBounds2, uBounds2)

`j`	Apply over this integer, the element that will be the largest in magnitude.
`muVec`	Mean vector of test statistics under the alternative (assuming it's MVN).
`sigMat`	Covariance matrix of test statistics under the alternative (assuming it's MVN).
`lBounds1`	A 3J-2 vector of lower bounds for the first integral (see paper), bounds will be longer than for performIntegralLower1.
`uBounds1`	A 3J-2 vector of upper bounds for the second integral (see paper).
`lBounds2`	A 3J-2 vector of lower bounds for the first integral (see paper).
`uBounds2`	A 3J-2 vector of upper bounds for the second integral (see paper).
