Helper for projecting based on [Ledger](http://www.ledger-cli.org/) format.

## Usage

To make a new Projection object, use `Ballista.new(entries: my_config)`. my_config should be a hash of projection entries, like this:

```

- name: Pay Check

  when:

  - 15

  - 30

  actions:

    Expenses:Taxes:federal_income: $729.26

    Expenses:Taxes:va_income: $215.14

    Expenses:Taxes:social_security: $299.46

    Expenses:Taxes:medicare: $70.04

    Assets:Checking:simple: $2739.10

    Assets:401K:Trad:work: $772.00

    Income:Salary:work: $-4825.00

- name: Automatic transfer to Savings

  when: 2

  actions:

    Assets:Savings:ally: $1000.00

    Assets:Checking:simple: null

- name: Rent

  when: 2

  actions:

    Expenses:Bills:rent: $2800.00

    Assets:Checking:simple: null

```

To do a projection, call `.project(start_dt, end_dt)` on your created object. The dates should be Ruby Date objects.

The returned object will be a Ledger journal, courtesy of [libledger](https://github.com/akerl/libledger). As such, you can inspect the .entries as well as use .to_s or puts to print it in ledger text file format.
