failing test for 2 to II
guard clause for 5 to V, passing test for II"
add recursive call for calculating roman numeral I remove guard clause for 1
set arabic,roman equal to [1, "I"]
add for 5 "V", find method to find input that is greater than or equal to the arabic number
abstract conversion into its own method
abstract conversion factors from the conversion method
rename conversion constant to conversion_factors
move test to numerical order
4 is returning IIII instead of IV
set 4 to iv in conversion factors constant
move test to numerical order
9 converts to VIV instead of IX
decided to test 10 instead of 9, 10 receives VV instead of X
10 now converts to X
9 converts to VIV instead of IX
9 now converts to IX
move test in numerical order
50 doesn't returns L
50 converts to L
