File metadata template

The following template should be at the top of every DistArray file:

"""A one-line description.

A longer description that spans multiple lines.  Explain the purpose of the
file and provide a short list of the key classes/functions it contains.  This
is the docstring shown when some does 'import foo;foo?' in IPython, so it
should be reasonably useful and informative.

# [remove this comment in production]
#
# List all imports, sorted within each section (stdlib/third-party/distarray).
# For 'import foo', use one import per line.  For 'from foo.bar import a, b, c'
# it's OK to import multiple items, use the parenthesized syntax 'from foo
# import (a, b, ...)' if the list needs multiple lines.
