Add code coverage

Yeah, coverage is poor right now. I know I know...

+These scripts provide a simple way to generate HTML reports of the code coverage
+of your Xcode 4.5 project.
+For a detailed blog post, see http://qualitycoding.org/xcode-code-coverage/
+
+
+Installation
+============
+
+1. Fork this repository; you're probably going to want to make your own
+modifications.
+2. Place the XcodeCoverage folder in the same folder as your Xcode project.
+3. [Dowload lcov-1.10](http://downloads.sourceforge.net/ltp/lcov-1.10.tar.gz).
+Place the lcov-1.10 folder inside the XcodeCoverage folder.
+4. Get Xcode's coverage instrumentation by going to Xcode Preferences, into Downloads, and installing Command Line Tools.
+5. In your Xcode project, enable these two build settings at the project level
+for your Debug configuration only:
+  * Instrument Program Flow
+  * Generate Test Coverage Files
+6. In your main target, add a Run Script build phase to execute
+``XcodeCoverage/exportenv.sh``
+
+A few people have been tripped up by the last step: Make sure you add the
+script to your main target (your app or library), not your test target.
+
+
+Execution
+=========
+
+1. Run your unit tests
+2. In Terminal, cd to your project's XcodeCoverage folder, then
+
+        $ ./getcov
+
+If you make changes to your test code without changing the production code and
+want a clean slate, use the ``cleancov`` script:
+
+    $ ./cleancov
+
+If you make changes to your production code, you should clear out all build
+artifacts before measuring code coverage again. "Clean Build Folder" by holding
+down the Option key in Xcode's "Product" menu.
+
+
+Modification
+============
+
+There are two places you may want to modify:
+
+1. In envcov.sh, ``LCOV_INFO`` determines the name shown in the report.
+2. In getcov, edit ``exclude_data()`` to specify which files to exclude, for
+example, third-party libraries.
