    [✓] 5. Replace Promises
    [✓] 6. Identifiers, Interfaces and Outputs

TO-DO
-   Cache options(standardTTL & checkPeriod as of now, maybe forceString)
-   Timed loop that checks each key to see if it needs to be updated
    or has expired(has exceeded its ttl)
-   Delete the key or update its value if the previous condition is met
-   Update the interfaces, and indentifier names
-   Uniform outputs and errors, update the error templates, make throwing
    errors more efficient

-   Update the documentation - consistent use of terminology, make it more 
    comprehensive
-   comprehensive README and logo
-   publish package
