Function type naming conventions

[Raab, Donald]

My thought experiment from a month or so ago:

https://github.com/goldmansachs/gs-collections-kata/tree/solutions-java8-jcf/src/test/java/blocks

What we have in production today:

https://github.com/goldmansachs/gs-collections/tree/master/collections-api/src/main/java/com/gs/collections/api/block

The number of interfaces are growing substantially in GSC 3.0 as we finish up primitive lists, sets, bags, stacks and maps.
