Issue 71

Hey @justinsgithub

Does this handle other files/folders this library generates? or just the schemas folder?

[justinsgithub]

@omar-dulaimi

it handles all files and folders generated by placing them in a folder called "schemas", inside of the directory specified by the user (or the default directory if user does not specify one).

The "schmas" directory just adds a layer of protection so that user does not accidentally delete their own files by specifying a non-empty directory in their project

"schemas" was just a name from the top of my head at the moment
