I migrated the modification to our Plutus implementation such that the
getTransactionTableCursor() would now return a transaction table, where each
transaction is also assoicated with either checking or saving account for a
particular user. I have only tested the modification in the test bank database
workspace, but I will test it later on.
I inserted a code snippet in User.java and provide an example of fetching the
type of bank account from the usr's transaction table. Hopefully, everything
will work out well.
