[Ann] New version of StateSpecs 2.0

Pragma based approach allows to write very natural expressions like

1 should be an instance of: Number 

But it is completely not practical because it is impossible to work with such code as with any other. No easy way to find senders or implementors of expressions. It is difficult to understand how it works. It's hidden magic. 

So now this approach is extracted to separate package as nice experiment on what can be done with smalltalk.

And legal approach now is to use normal keywords like:

1 should beInstanceOf: SmallInteger

1 should beKindOf: Number

With this you can easily find implementors and get full list of defined expressions. (look at class SpecOfShouldExpression)

1 should be between: 10 and: 50

#(1 2) should be isEmpty

• properties chain validation. You can send any series of messages to "object where" to write should expression for internal property:

(1@3) where x should be: 1
(0@1 corner: 10@20) where origin x should be: 0

• unordered equality for collections and explicit order sentence:

#(1 2) should equal: #(2 1) "not fail"

(1 2) should beOrderedEqualTo: #(2 1) "fail"

Idea that in tests you usually put as less details as possible. And only if you really need specific behaviour you write it requirement explicitly. 

• better failures descriptions similar to existed assertions:
  

1 should be: 2

=> Got "1" but it should be "2"

1 should beInstanceOf: String

=> Got "1" but it should be instance of String

#(1 2) should be isEmpty

=> #(1 2) should be isEmpty

(1@3) where x should be: 10

=> Got "1" from (1@3) x but it should be 10

#(10 20) should include: 10 at: 1

#(10 20) should include: (Kind of: Number) at: 1

[1/0] should raise: ZeroDivide "not fail"

[1/0] should raise: Error "fail because explicit exception class is specified"

[1/0] should raise: (Kind of: Error) "not fail"

[self error: 'test'] should raise: errorInstance "fail because raised exception is not the same instance as errorInstance"

[1/0] should raiseError "not fail when any kind of errors was signalled"
