diffpy.utils - general purpose shared utilities for the diffpy libraries.
The diffpy.utils package provides general functions for extracting data from variously formatted text files as well as some PDF-specific functionality. These include wx GUI utilities used by the PDFgui program and an interpolation function based on the Whittaker-Shannon formula for resampling a bandlimited PDF or other profile function.
