Detailed Description

A simple class to hold the kernel(s) generated and the intermediate
data products.

kernel.ampwiseKernels are the kernels for each amplifier in the detector,
as generated by having LEVEL == 'AMP'

kernel.detectorKernel is the kernel generated for the detector as a whole,
as generated by having LEVEL == 'DETECTOR'

kernel.detectorKernelFromAmpKernels is the kernel for the detector,
generated by averaging together the amps in the detector

The originalLevel is the level for which the kernel(s) were generated,
i.e. the level at which the task was originally run.
