# Example of how use Spreadsheet::WriteExcel to generate Excel outlines and
# grouping.
#
#
# Excel allows you to group rows or columns so that they can be hidden or
# displayed with a single mouse click. This feature is referred to as outlines.
#
# Outlines can reduce complex data down to a few salient sub-totals or 
# summaries.
#
# This feature is best viewed in Excel but the following is an ASCII
# representation of what a worksheet with three outlines might look like.
# Rows 3-4 and rows 7-8 are grouped at level 2. Rows 2-9 are grouped at
# level 1. The lines at the left hand side are called outline level bars.
#
#
#             ------------------------------------------
#      1 2 3 |   |   A   |   B   |   C   |   D   |  ...
#             ------------------------------------------
#       _    | 1 |   A   |       |       |       |  ...
#      |  _  | 2 |   B   |       |       |       |  ...
#      | |   | 3 |  (C)  |       |       |       |  ...
#      | |   | 4 |  (D)  |       |       |       |  ...
#      | -   | 5 |   E   |       |       |       |  ...
#      |  _  | 6 |   F   |       |       |       |  ...
#      | |   | 7 |  (G)  |       |       |       |  ...
#      | |   | 8 |  (H)  |       |       |       |  ...
#      | -   | 9 |   I   |       |       |       |  ...
#      -     | . |  ...  |  ...  |  ...  |  ...  |  ...
#
#
# Clicking the minus sign on each of the level 2 outlines will collapse and
# hide the data as shown in the next figure. The minus sign changes to a plus
# sign to indicate that the data in the outline is hidden.
#
#             ------------------------------------------
#      1 2 3 |   |   A   |   B   |   C   |   D   |  ...

#       _    | 1 |   A   |       |       |       |  ...
#      |     | 2 |   B   |       |       |       |  ...
#      | +   | 5 |   E   |       |       |       |  ...
#      |     | 6 |   F   |       |       |       |  ...
#      | +   | 9 |   I   |       |       |       |  ...
#      -     | . |  ...  |  ...  |  ...  |  ...  |  ...
#
#
# Clicking on the minus sign on the level 1 outline will collapse the remaining
# rows as follows:
#
#             ------------------------------------------
#      1 2 3 |   |   A   |   B   |   C   |   D   |  ...
