setup zk project
some refactoring to allow ExternalConfig to modify raw set of command line args; existing unit tests pass, no test of new functionality
fix help message and add test
update docs
each argument also knows how to convert itself back to a string, via the parser, for saving them back out
add PropertiesConfig, minor change to parse method to clean up internals
basic reading & saving from zookeeper
basic unit test, helpers for checking if node exists & recursively deleting
basic loading from zookeeper working (with just one path)
get it working with multiple zookeeper paths
get saveConfig working for properties
final bits for combining properties & zookeeper, plus tests
turning zookeeper tests off by default
bump up version number (should have done that a while ago)
FieldArgs should silently ignore fields it doesn't know how to parse (consistent with 0.1); add FieldArgsExceptionOnUnparseable to aggressively throw exceptions on unsupported types
update some versions
cleanup build file a bit
simple example program
update README
add toString on ArgAssignable
