parallel execution in lab is limited in experiment level

[cades]

Since given encourages using context, this design is a huge disadvantage to given framework.

Consider manage name stack, and do not use lab.experiment. just use lab.test, and generate test name on the fly.

this feature may be enabled by config, default to false.

This feature can be done in lab by modifying this line.
Just replace Items.serial with Items.parallel.

However doing this violates most JS developers' common sense, since lab itself (so as jasmine, mocha and many other testing frameworks) does not rely on context object (this).

So, implement this feature into respec-given-lab makes more sense.

[cades]

It can be a config, for example:

var given-lab = require('respec-given-lab')(lab, { parallelCrossSuites: true })

the config name comes into my mind:

• parallelCrossSuites
• virtualSuite
• flatten
• inlineSuite
• expandSuite

another design is exposing a different describe:

var {inlineSuite, Given, When, Then} = given-lab
var describe = inlineSuite

---

I prefer inlineSuite and expandSuite since the name told just what they do. parallelCrossSuites may mislead if the user didn't use --parallel.

---

the second approach may generate confusing test label, since we maintain a name stack beside lab's.

for example:

inlineSuite("level 1", function() {
    describe("level 2", function() {
        inlineSuite("level 3", function() {
            Then("test A", => "ok" )
            Then("test B", => "ok" )
        })
    })
})

will generate

level 2 level 1 level 3 test A
level 2 level 1 level 3 test B

I can not coordinate these two stack. so approach 1 is the way to go.
