* add transform and checkedTransform tests add Transformer and CheckedTransformer validators * Eliminate the Validator description string, some code cleanup add tests Make Validators a full Object and remove friend, move to descriptions instead of overriding type name. update validators to actually merge the type strings and use all validators in the type outputs rework join so it works without the start variable, allow some forwarding references in the validator types, some tests for non-copyable maps, and transforms merge the search function and enable use of member search function, make the pair adapters forwarding instead of copying * add a few more tests and documentation fix some gcc 4.7 issues and add a few more test cases and more parts of the README Work on ReadMe and add Bound validator to clamp values * updates to README.md * Add some more in TOC of README and fix style in Option.hpp
