/**
 *  spectrumDetect.cc
 *
 * A detection algorithm that searches in a single 1-D spectrum.
 *
 * INPUTS: 
 *    image     -- an Image object, containing a 1-D image that has been 
 *                 processed such that its pValue array is defined.
 * OUTPUTS:
 *   The detection and mask arrays in image will be filled, according to 
 *   the location of the objects in the image.
 *
