A tiny example file.
Improvements to verify-balance operation. Tweaked account names.

Now actually checks verify operations that are dated after last
transaction.

Improved parsing of verify-balance lines (mainly error reporting).

Allow Revenue/Revenues as a substitute for Income in account names.
Added very small example file.
Improved --print-register so that running balance is shown first.

Output lines now look like this:
<date> <running-balance> <posting-amount> <posting-account> <description>
Trivial.
