Add ability to import an OFX transaction directly into YNAB

[IndexEng]

Objective

Write a method that allows the upload of a single transaction that is extracted from an OFX file.

Inputs

The input to this system is a Transaction object that is produced by the ofxparse library. The transaction object contains:

• 'payee'
• 'type'
• 'date'
• 'amount'
• 'id'
• 'memo'
• 'sic'
• 'mcc'
• 'checknum'

Processing

Main processing required is to emulate the import ID to ensure transaction imports are not duplicated. This will also ensure that transactions manually and automatically imported will not be duplicated.

Outputs

The YNAB endpoint accepts transaction information in the following format:

"transaction": {
    "account_id": "string",
    "date": "string",
    "amount": 0,
    "payee_id": "string",
    "payee_name": "string",
    "category_id": "string",
    "memo": "string",
    "cleared": "cleared",
    "approved": true,
    "flag_color": "red",
    "import_id": "string"
  }

This will be achieved using a method called construct_ofx_transaction. It passes in a YNAB compatible account_id and the ofx transaction. A separate method will need to be constructed that determines the YNAB account_id given a particular account number.
