Summary

Added prerequisites for exercises listed in issue #984:

  • rectangles: arrays, loops, numbers, conditionals

Note: Most exercises in issue #984 already had prerequisites configured, so only rectangles was updated.

Fixes #984

Updated the instructions to clarify that a zipper consists of:
1. The path/thread leading to the focused node
2. The focused subtree

This resolves the misleading description that a zipper 'contains
a data structure and a pointer into that data structure.'

Fixes exercism#777
Added prerequisites for:
- roman-numerals: strings, loops, numbers, conditionals
- square-root: numbers, arithmetic-operators
- all-your-base: numbers, arrays, loops, arithmetic-operators
- queen-attack: classes, numbers, conditionals
- react: classes, numbers, arrays, functions
- zipper: classes, recursion, trees, numbers, arrays
Added prerequisites for:
- bowling: classes, arrays, conditionals, numbers, loops
- strain: arrays, functions, array-transformations
- flatten-array: arrays, recursion
- nth-prime: numbers, loops
- sieve: numbers, arrays, loops
- rotational-cipher: strings, numbers, conditionals
- diffie-hellman: numbers, arrays, loops, arithmetic-operators
- affine-cipher: strings, numbers, arrays, loops
- atbash-cipher: strings, arrays, loops
- robot-simulator: classes, strings, numbers, conditionals
- sum-of-multiples: numbers, loops
- change: numbers, arrays, loops, algorithms
