reformatting the comments in problem 27
Made solutiont 27 quicker by making value of B only check prime values. Also increased speed of primality check by performing mod 2 operation beefore evaluating square root
Adding solutions to problem 28 and 29. Also altering code in previous solutions to use style of solutions now.
Refactoring solutions to use a main method and a calculateSolution method rather than having the solution calculate and print and timecheck
