A simple testing framework for lldb using python's unit testing framework.

Tests for lldb are written as python scripts which take advantage of the script
bridging provided by LLDB.framework to interact with lldb core.

A specific naming pattern is followed by the .py script to be recognized as
a module which implements a test scenario, namely, Test*.py.

To specify the directories where "Test*.py" python test scripts are located,
you need to pass in a list of directory names.  By default, the current
working directory is searched if nothing is specified on the command line.

An example:

[14:10:20] johnny:/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v example
test_choice (TestSequenceFunctions.TestSequenceFunctions) ... ok
test_sample (TestSequenceFunctions.TestSequenceFunctions) ... ok
test_shuffle (TestSequenceFunctions.TestSequenceFunctions) ... ok
