* fix: improve Project Euler descriptions and test case
Improve formatting of Project Euler test descriptions. Also add poker hands array and new test case for problem 54
* feat: add typeof tests and gave functions proper names for first 100 challenges
* fix: continue fixing test descriptions and adding "before test" sections
* fix: address review comments
* fix: adjust grids in 18 and 67 and fix some text that reference files rather than the given arrays
* fix: implement bug fixes and improvements from review
* fix: remove console.log statements from seed and solution
Either improved the algorithm or reduced the difficulty for the slowest
tests. All these pass with testProtectTimeout = 500, so should be safe
on most machines with the current timeout of 2500.
