caps-cli initialize only works in ModelCatalogInsertion directory

[Cmheidelberg]

Unless there is some scope of this project I am missing I would highly recommend doing away with the ModelCatalogInsertion/files directory and just have ModelCatalogInsertion work within the current directory the user is in (similar to how wcm used to work). So, if a user runs caps-cli initialize in their desktop it will just make the initialize_schema.json file there. wcm make-yaml shows an example of this.

If you dont want to use the current directory and instead want a standardized place for files then files should be put a specified location specified from the user's root directory. ie: C:/Users/Admin/.caps-cli. The wcm credentials file is an example of this. It is located in C:/Users/Admin/.wcm. Though there needs to be an error or warning thrown if the file cannot be found

Also since ModelCatalogInsertion will eventually be installed from pip there should be no need for the user to cd into the cloned repo

In case you want the error message for this:

$ caps-cli initialize
