* Initial moving * Initial package __init__.py * Use relative imports * Correct imports for tests * Rename main.py -> __main__.py * Use relative imports in main * Refactor cli to be used with setuptools * Add basic setup.py * Fix test_memory import * Fix test_cpu_manual imports * Correct iterpickle import * Use manticore console_script installed by setuptools * Make travis install our package for integration cli tests * Refactor model hooks dynamic import for being in pkg * Correct import * Rm empty line * Fix coverage test paths
