Improved Scaladoc of Inspectors.
Fleshed out Scaladoc primarily of Matchers.
Added tests and Sortable typeclass to enable be sorted syntax on String.
Added remaining tests for Sortable strings.
Bumped rev to 2.1.0-RC2.
init ver. Added tests that ensure FlatSpec and WordSpec can either
mix in or import (above) Matchers.
inti ver. more test classes that ensure matchers can be either
mixed into or imported above FlatSpec and WordSpec, which broke
in 2.1.RC1.
Changed directory names for generated code that is now getting a conflict, I believe because
we import Matchers instead of mixing it in now.
Merge branch '2.1.x' of https://github.com/scalatest/scalatest
