Replace tuples for arrays

[swfsql]

Removes the features:

• usize as a Pattern and Shape/Stride for 1-dimensioned Arrays.

  • but usize may still be used as indexing for 1-dimension Arrays.

• n-sized tuples as a Pattern and Shape/Stride for n-dimensioned Arrays.

• Closes [de-feature request] tuples for const-defined dimensions #622

  • Updated to [de-feature request] tuples for const-defined dimensions #622 (comment)

• The documentation wasn't extensively reviewed.

I'm skeptical of this change, but my vote doesn't necessarily matter.

Reasons:

1. Less typing is better. Array::zeros(10) is good, no extra brackets needed. ((1, 2)) is less typing than ([1, 2]) because it is easy to repeat a keystroke
2. It breaks about all code out there. As usual, try to deprecate a release before, if the change is to be done.
