Find FreshBooks vendors who also give through Bloomerang

**Objective:** Find vendors in FreshBooks who are also donors in Bloomerang, looking at up to `{max-vendors}` vendors (default 50) for FreshBooks business `{company}` (optional).

**Step 1: List vendors**

Call `freshbooks-get-vendor` (FreshBooks server) with `max-records` set to the limit and `company` if given. Keep each vendor's `vendor-name`, `email` and `id`. Skip vendors with no email and count them.

**Step 2: Look each vendor up as a donor**

For each vendor with an email, call `bloomerang-get-constituent` (Bloomerang server) with `primary-email` set to that email. For each match, call `bloomerang-get-transaction` (Bloomerang server) with `account-id` set to the constituent `id` and add up `amount` for the totals.

**Step 3: Report**

A table of vendor name, vendor email, Bloomerang `full-name`, `account-number`, number of gifts, total given and most recent gift `date`. Then list the vendors with no email and the count of vendors with no Bloomerang match.

**Rules & Guidelines:**

* `freshbooks-get-vendor` is on the FreshBooks server; `bloomerang-get-constituent` and `bloomerang-get-transaction` are on the Bloomerang server.
* Read only. Never call any add, update or delete tool on either server.
* Match on email only; do not guess from names.

**Validation:**

* If `freshbooks-get-vendor` returns nothing, stop and say so.
* If a vendor matches more than one constituent, list all of them and do not total the gifts.
