Last crude test for now, loops thought “methods” and a comparison string (to dog). output is the similarity “score” for the method and strings. Added a little sleep so not to be “rate-limited” out of the loop

```
irb(main):075:0> methods

irb(main):063:0> compare=["cat", "asteroid", "rock fish", "submarine", "gemstone","dog food","chatgpt"]
=> ["cat", "asteroid", "rock fish", "submarine", "gemstone", "dog food", "chatgpt"]

irb(main):071:2* Embeddings.test_strings({string1:"dog",string2:phrase,method:method}); sleep 5

Same thing, but change the order of the loops, for fun…

```
irb(main):076:1* methods.each do |method|
irb(main):077:2* compare.each do |phrase|
irb(main):078:2* Embeddings.test_strings({string1:"dog",string2:phrase,method:method}); sleep 5
irb(main):079:1* end

One could argue that, in this data set, the Manhattan method is preferable; but it’s a matter of use case and preference, etc.
