.TODO.multiple_shrinking.txt

+ support array of GeneratedValues being returned in Shrinker\Random (use only the first one)
+ extend Generator\Integer to provide multiple values (-1, /2)
+ allow configuration of method of ShrinkerFactory to call ('random' for now)
+ create an acceptance test in examples/ adding a log listener to check how it is shrinking
+ there, try to use 'multiple'
+ implement Shrinker\Multiple
++ here there will be many things to do
- composable Generators must support this in their shrink()
++ AssociativeArray
++ Bind
++ Elements
++ Frequency
++ Map
++ OneOf
++ Sequence
--- relies on Vector which relies on Tuple... and when there are more than a few elements there is a combinatorial explosion of options for shrinking
++ Set
++ Subset
++ SuchThat
++ Tuple
--- Tuple::contains()
++ Vector
+ extract Shrinker interface
- GeneratedValue rename
-- extract GeneratedValue interface, and rename GeneratedValue to GeneratedValueSingle or SingleGeneratedValue
-- use smallestStep() or similar instead of last() and implement it also on GeneratedValue
-- complete first Phunkie PRs
+ check GeneratedValue with Onebip guys
+ check TODO comments in the diff
- extract common patterns of usage of GeneratedValue|GeneratedValueOptions into methods on these Value Objects
- priority in shrinking: when evaluating options order counts a lot. The cartesian product can be improved?
