# === Some helper functions for displaying cell references ===
# Note that a "non-standard" syntax is used in row and column
# components in relative references.
# For example, consider a relative reference: up two rows, right 3 columns.
# On screen, with cursor in cell D10, this would appear as G8.
# On screen, with cursor in cell Z100, this would appear as AC98.
# On screen, with cursor in cell A1, this would appear as D65535.
# These functions will display such a reference as [@+3,#-2].
# "@" refers to the unknown base column.
# "#" refers to the unknown base row.
#
# I'm aware of only one possibility of a sheet-relative component in
# a reference: a 2D reference located in the "current sheet".
# xlrd stores this internally with bounds of (0, 1, ...) and
# relative flags of (1, 1, ...). These functions display the
# sheet component as empty, just like Excel etc.
