# This is the default loader for IOWA applications.
# The DiskLoader loads templates from disk.
#
# A Loader is responsible for:
#   - Returning a template's contents, given a path to the template.
#   - Returning the last modification tome of a template, given a path
#     to the template.
#   - Taking a path, and determining if it is a path that the loader can handle.
#   - Returning a priority number indicating the order in which the template loader should have a chance at the path.
