Added the blank series file.
Wrote the fibonacci function using a flat for loop method and placeholder
variable.
Added the lucas series in a similar fashion.
Changed the index to a zero index to match python notation, and added
functionality at index zero.
Added a final sum_series function that can mimic the fibonacci, lucas, or
any other sum type series.
Added a test block to validate the code.
Everything appears to work perfectly.
Final code clean up. Added a few more tests to the code validation.
