Removing Credits/One Time Charges

[Lucas Heuman]

Hello, I"m using Freeside 1.4.1 and I used the "one time charge" and post
credit to make some billing adjustments for a good deal of my customer base.
I now have to remove each one of these and reprint the invoices, now I see
that in the API they Delete package is not implimented for removing the
package.. I was wondering what I need to remove from the database to
"cleanly as possible" cut these mistakes out.
