Revamp for golang/go#77273

[earthboundkid]

Now that there can be generic methods, everything can/should be rewritten.

[earthboundkid]

import "github.com/earthboundkid/should"

be := should.Strict(t)
be.Equal(x, y)
x := be.Ok(somethingThatErrors())

etc.

[earthboundkid]

Have chaining be.Equal(x, 1).NotEqual(x, 2).

[earthboundkid]

Name ideas:

• synonyms for assert?
• Should?
• dearu (too Japanese?)
• Copula (sounds dirty)

[earthboundkid]

be := check.Strict(t)

[earthboundkid]

Remember to add #8 be.OK.
