CTCP6-145: TIS - Changelog to be automated from Excel Spreadhseet from DDNTA analysis output

[tudorsonycx]

For the script to work consistently, we also have to make sure that the [DDNTA Analysis] document (https://docs.google.com/spreadsheets/d/12FVynQheNWuQOcFd0nSVaysDQFToFDP1Vl27xJFYyKk/edit?gid=0#gid=0) is consistent in the way that it's written before converting it to CSV and passing it to the script.

• ideally only one effect (removed, added or changed) denoted by a line in delta
• the delimiter between the path and the description is always the final '>' character and shouldn't be used for any other purpose
• valid lines to be considered start with '-', followed by the path, followed by the description

Adhering by these rules when writing the document keeps things readable and consistent!

Regarding the first condition, for example:

• MESSAGE > HOUSE CONSIGNMENT > CONSIGNMENT ITEM>>> GOODS MEASURE > Rule 'B2101' has been deleted, 'Optional (O)' has been changed to 'Required (R)'

should be split into 2 items (and optionally remove the 2 extra '>' after 'CONSIGNMENT ITEM')

• MESSAGE > HOUSE CONSIGNMENT > CONSIGNMENT ITEM > GOODS MEASURE > Rule 'B2101' has been deleted.
• MESSAGE > HOUSE CONSIGNMENT > CONSIGNMENT ITEM > GOODS MEASURE > 'Optional (O)' has been changed to 'Required (R)'.

I've also pushed a copy of the DDNTA Analysis doc in CSV format that I modified to follow the above rules.
