986e695bd5 Made arrays strict by default; please merge to release
* Added parameter `array-strictness', default #t

* Added `array-default-strict!' and `array-default-strict', which act
  like the functions without "default" in the name when
  `array-strictness' is #t; otherwise they do nothing

* Lots of small changes to existing array functions, mostly to ensure
  computations are done using nonstrict arrays, but return values are
  strict when `array-strictness' is #t

* Added strictness tests

* Added tests to ensure untyped code can use `math/array'

* Rewrote `array-map' exported to untyped code using untyped Racket

* Rearranged a lot of `math/array' documentation

5a43f2c6bc Finished array documentation!
Cleaned up other docs in preparation for alpha-testing announcement

Created `math/utils' module for stuff that doesn't go anywhere else (e.g.
FFT scaling convention, max-math-threads parameters)

Reduced the number of macros that expand to applications of `array-map'

Added `flvector-sum', defined `flsum' in terms of it

Reduced the number of pointwise `flvector', `flarray' and `fcarray' operations

Reworked `inline-build-flvector' and `inline-flvector-map' to be faster and
expand to less code in both typed and untyped Racket

Redefined conversions like `list->flvector' in terms of for loops (can do
it now that TR has working `for/flvector:', etc.)

f2dc2027f6 Initial math library commit. The history for these changes is preserved
in the original GitHub fork:

  https://github.com/ntoronto/racket

Some things about this are known to be broken (most egregious is that the
array tests DO NOT RUN because of a problem in typed/rackunit), about half
has no coverage in the tests, and half has no documentation. Fixes and
docs are coming. This is committed now to allow others to find errors and
inconsistency in the things that appear to be working, and to give the
author a (rather incomplete) sense of closure.
