Variable Search Ability

Please read the previous release for more info, but this is a mini-update with a few bug fixes (refer to commits)

Whenever Yahoo Finance returned a number without a 'k' or 'M' or 'B' it would cause an error, so that was fixed.

The main feature that was added, was now you are able to search for any amount of time you wish not just ninety days! :)

Initial Release

Please read the readme for more info delete the file for your operating system. If you are on macOS, you may need to made the file executable with chmod. More about that in readme.md. Unfortunately, there is no compiled binary for linux and you must make it yourself, but you may try the macOS one if you wish.
