e0d037d529 Correct closing paren for meditations (#118) 
The closing paren for meditations occurred after the second-to-last
koan instead of the last one, so the test on the last one would never
be executed.

4d4cb3b93a First encounter with nil 
In 02_strings.clj, the answer to

   (= __ (string/index-of "hello world" "bob"))

is `nil` but `nil` is not obvious for somebody who
never saw it before. This step introduces it.

a8fe71e26f Update java string methods to clojure functions 
With Clojure 1.8.0 finally those string methods now have corresponding
Clojure functions.

Of note here is that the clojure.string/index-of function responds
with nil if nothing is found and not -1 as .IndexOf previously did.

d30e324bcd src/koans/21_partition.clj: correct meditation doc 
The meditation was misleading because calling `(partition-all 3 (range 5))` returns `((0 1 2) (3 4))` results in sequences having <=3 elements , not strictly less than.

569aa5e85b Remove unnecessary call to partial in second koan 
juxt returns a function that takes a variable number of arguments, so a
partial taking one argument does not need to be created.

e96ccc4494 Switch variable from index to x to avoid confusing syntax highlightig. 
index is a clojure.set function and ended up highlighted for me, sending me
down a rabbit hole of confusion. Avoid this with a more generic variable name
consistent with other Koan files.

68dcde939e Make if-not example clearer, fix the answer keys 
I felt the example wasn't very clear as the conditional returned the
quoted form of `doom` when it evaluated to true or false. This way the
user needs to find a value that satisfies the if-not conditional so it
returns `doom` and not `more-doom`.

92c7f8b2f0 Added one test to the polymorph suite (test name usage) 
* added one tests that verifies that the diet function also
  accesses the name value of the map (before it was possible
  to just return "Bambi eats veggies." for the herbivore diet
* since this is not the main purpose of these specs added just
  this one and not extra specs for default/carnivore as I didn't
  want to bloat it, but could add those as well if desired
