DoubleSymmetricBackward1DFFT represents the backward discrete fourier transform of a 1D real signal vector, and
inverses packed conjugate symmetric signals back to the real domain.

Remarks
The class DoubleForward1DFFT creates packed conjugate symmetric signals, and it is these signals that
are reversed by this class.
The backward FFT is defined to have a negative exponent in the transform with a default
scale factor of 1.0.
To gain greater efficiency in transforming sets of same-length signals, first arrange signals row-by-row in an
array, and then use the FFTInPlace(double[,] arrayinout) method.
