Detailed Description

Abstract base class for an array of pixel values.

For writing pixels out with the C-based cfitsio API, it's helpful to have a type-agnostic holder of the pixel values (because although we can template on the array type, the output type can be configured at run-time, which means we can't use ndarray::Array as the carrier). This is essentially a C++-ish void* array.
