| Wrap Text |

| Given a long string and a column width, break the string on spaces into a list of lines such that each line is no longer than the column width. |

| Input: |
| text: The starting text. |
| cols: The target column width, i.e. the maximum length of any single line after wrapping. |
| |
| Precondition: |
| cols > 0. |
| |
| Output: |
| An ordered list of strings, each no longer than the column width, such that the concatenation of the strings returns the original text, |
| and such that no word in the original text is broken into two parts unless necessary. The original amount of spaces are preserved (e.g. spaces |
