Transaction data need to be provided in CSV files contained

CSV files can be produced by any decent spreadsheet software. Spreadsheet software can be used to manipulate exported price, exchange and wallet data into the correct format.
Empty rows are allowed. Additional columns for comments etc. are allowed and ignored.
Please see the ./examples directory which contains an example of how data
should be provided.
Buying selling shares and other acquisitions or disposals can be provided in
the ./gains directory in as many CSV files as desired. The CSV files can be
named anything as long as they end in .csv.

Calcuations are done for a particular period of time. The start and end dates
