# The coords attribute is a tuple of the form:
# (shtxlo, shtxhi, rowxlo, rowxhi, colxlo, colxhi)
# where 0 <= thingxlo <= thingx < thingxhi.
# Note that it is quite possible to have thingx > nthings; for example
# Print_Titles could have colxhi == 256 and/or rowxhi == 65536
# irrespective of how many columns/rows are actually used in the worksheet.
# The caller will need to decide how to handle this situation.
# Keyword: IndexError :-)
#
#
# The components of the coords attribute are also available as individual
# attributes: shtxlo, shtxhi, rowxlo, rowxhi, colxlo, and colxhi.
#
# The relflags attribute is a 6-tuple of flags which indicate whether
# the corresponding (sheet|row|col)(lo|hi) is relative (1) or absolute (0).
# Note that there is necessarily no information available as to what cell(s)
# the reference could possibly be relative to. The caller must decide what if
# any use to make of oREL operands. Note also that a partially relative
# reference may well be a typo.
# For example, define name A1Z10 as $a$1:$z10 (missing $ after z)
# while the cursor is on cell Sheet3!A27.
# The resulting Ref3D instance will have coords = (2, 3, 0, -16, 0, 26)
# and relflags = (0, 0, 0, 1, 0, 0).
# So far, only one possibility of a sheet-relative component in
