Bounded Float and Int

[SylvainCorlay]

@minrk This allows defining a min and max attribute to a Float trait type.

(I will add a test if you are fine with this.)

I think it makes sense. I would do the same on Integer, though.

[SylvainCorlay]

Added a bounded Int. In Python 3.0, int does not really have a maximum value. Hence the implementation is a bit different than for Float.

lesser -> less

The error messages should also include the value that it was trying to set, I think, by analogy with the type mismatch error messages:

"The '%s' trait of %s instance must be %s, but a value of %s was specified."

[SylvainCorlay]

@takluyver as per you suggestions.

[takluyver]

repr_type() will return something like 200 <class 'int'>. Given that at this point it must be the correct type, we can just show its repr with %r in the format string.

[SylvainCorlay]

done.
