Add a function that uses an array/1 value to construct an array2d/1 value
without allocating new memory for the element storage or traversing the
elements.
library/array2d.m:
Add a function that creates an array2d/1 from an array/1 value
Fix minor documentation issues:
- re-order the declarations so that of from_lists/1 is directly below
that of array2d/1.
- s/a/an/ in a few spots.
- add missing apostrophes.
NEWS:
Announce the new function.
tests/hard_coded/Mmakefile:
tests/hard_coded/array2d_from_array.{m,exp}:
