Integration tests for Crypto-Conditions

These tests are for the Crypto-Conditions functionality in Komodod, using Hoek as a tool to create and sign transactions.

The tests use Python as a scripting language and each one should "just work" given Linux and a 2.7+ Python interpreter. Each file prefixed with "test_" is a test case.

The tests require hoek to be on the $PATH. Included is a script to perform a complete installation of hoek.
