The Jacobian determinant for transformation should take absolute value #126

Currently, JIM computes the density change in the parameter space due to transformation by calculating the Jacobian determinant. The absolute value of the Jacobian determinant should be used; otherwise, feeding it into the calculation of the log Jacobian determinant may result in nan values.
