# utils to overlay DATA to simulation
#
# in order to use this function:
# import it:
# import svd.overlay_utils as svdou
# and then use it to:
# 1) prepare the input files
# 2) actually overlay the data
#
# IMPORTANT: default paths are for KEKCC only!!
#
# examples are in svd/examples/runOverlay.py
