Modified .gitignore, commented "koans/*" as I want to watch the koan files as I progress through them.
Added koans directory
clear and rake instead of just running rake
Added my own opening section to README to make it clear that this is not the original ready-to-answer Ruby Koans, but a repository with my answers.
First three solutions, asserting truth and that 1+1 equals 2.
Test 4: test_a_better_way_of_asserting_equality. Entered value for expected_value.
Test 5: test_fill_in_values: filled in space with what 1 + 1 should equal.
test 6: test_nil_is_an_object: Entered expected result for nil.is_a?(Object) which is true because Nil is in fact an object in Ruby.
Test 7: test_you_dont_get_null_pointer_errors_when_calling_methods_on_nil: For this test identified that calling an unknown method raises the exception NoMethodError and also provided the message (when can be found using the message method on the exception object)
Test 8: test_nil_has_a_few_methods_defined_on_it: nil? yep nil is a nil. .to_s returns "" an empty string, .inspect returns "nil".
Test 9: test_everything_is-an_object: 1, 1.5, "string", nil, and Object are all objects
Test 10: Provided strings for 123.to_s and nil.to_s
Test 11: objects_can_be_inspected: Inspect returns a human readible representation of the object.
Test 12: test_every_object_has_an_id: And this ID is an integer value. Which for obj.object_id.class is of the class Fixnum.
Test 13: test_every_object_has_different_id gave boolean for obj.object_id != another_obj.object_id
Test 14: test_small_integers_have_fixed_ids: The small integers have IDs set by a formula -- ID = 2i+1
Test 15: test_clone_creates_a_different_object -- true. While the contents of a clone may look the same, the clone is not the original.
