Bumped version to 3.0.0-SNAP2.
Throw NotAllowedException for be ===
Restore a test in TestCanceledExceptionSpec
Merge branch 'fail-deprecated-be-tripleequals' of https://github.com/gcberger/scalatest into 2.2.x
Changed error message given for be === syntax.
Merge branch '2.2.x' of https://github.com/scalatest/scalatest
Bringing in George's branch that expires the deprecation period for
the be === syntax by throwing NotAllowedException, because otherwise
old code that didn't get changed already could compile but just not work.

Added scalactic.math package and Percent type.
Drop "math" from in front of Ordering since I just added an org.scalactic.math package.
Add types in org.scalactic.numbers for positive and positive + zero ranges
Changed math to numbers in the sbt build file.
Added some tests for be === stack depth, which already passed, and fixed two
Specs that had been accidently made to be unable to instantiate.
Fixed some bugs in the PosSpec test, which sbt is not running currently, and
added a est and code for widening conversions from Pos to Int, Long, Float, Double,
Poz, LPoz, FPoz, and DPoz.
Modified build slightly to get sbt to run scalactic.numbers package tests, though
I don't understand why this change accomplished that.
Added + operator on Pos that takes Int, Long, Float, and Double.
Added tests and implicits to support adding *Pos and *Poz to Pos.
Removed ye olde org.scalatest.matchers.ShouldMatchers, which has been deprecated
since the 2.0 release, which came out over a year ago. King of sad to see them go.
Pulled in the latest changes from 2.2.x, which was the removal of
org.scalatest.matchers.ShouldMatchers, which was deprecated in 2.0,
release just over a year ago.
