/*
|
|
* ITFlow - importing a card or bank statement as expenses.
|
|
*
|
|
* A statement exported as CSV is read (any delimiter, a header row found
|
|
* among the first lines or none), its columns are guessed - the date, the
|
|
* description, the amount or separate money out and money in, a reference -
|
|
* along with the date format and whether charges are positive or negative,
|
|
* and the guess is remembered on the account for its next statement.
|
|
*
|
|
* Each line is matched to a vendor: first by what was picked for the same
|
|
* merchant last time (expense_import_rules, keyed on the start of the
|
|
* cleaned-up description), then by one of our vendors' names appearing in
|
|
* it, with the category and client that came with it, or the vendor's last
|
|
* category. Lines with no match suggest a new vendor named from the text.
|
|
*
|
|
* Every line has a key (expense_import_key) from the account, date, amount,
|
|
* text and which repeat of those it is in the file, so the same statement
|
|
* can't bring a line in twice. A line not imported before but with the same
|
|
* amount on the same account within a few days of an expense entered by
|
|
* hand looks entered already - left out unless ticked, and if left out the
|
|
* hand-entered one takes its key, so the next statement knows it too.
