preliminary work on getting PHPUnit testing working
PHPUnit! Tests moved over from orphaned Leadership branch, leftover var_dump removed from IOPYaml library
adding the little python yaml test-parser I wrote.
switched to os.path.realpath to find the yaml stuff for testing.
IOPYaml now supports YML front matter. A few tests included
refactored out all load_yaml calls to IOPYaml::load, removed corresponding tests, other minor refactoring
namespaced Logger, moved it into app/lib/IOP and psr2'd it
Namespaces! Significant refactoring and re-organization of our library files. PSR2ing and general cleanup

Tweaking the yaml tree

Merge branch 'content' into newhome

Conflicts:
	app/lib/IOP/Views.php
YAML files are now cached to JSON on load. Page rendering times were cut in half.
Merge branch 'home_images' into newhome

Conflicts:
	app/lib/IOP/IOPYaml.php
Relocated all cache files to a common top-level /cache directory. There may
still be some permissions issues since Ruby (Sass/Compass) seems to write
from a different user than PHP does.
Merge branch 'yaml_cache' into newhome
Added the CACHE_DIR constant and allowed PHPUnit tests to override that value so we don't get permissions-related failures when running tests since PHPUnit runs as a different user than other web processes.
