Settings file is required to use the package

I cloned the repository and from within the project directory I pip installed flowcept in a Python environment. I tried to import the package with import flowcept but it gives the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/g/Desktop/ORNL/OLCF/flowcept/src/flowcept/__init__.py", line 3, in <module>
    from flowcept.configs import SETTINGS_PATH
  File "/Users/g/Desktop/ORNL/OLCF/flowcept/src/flowcept/configs.py", line 19, in <module>
    raise Exception(
Exception: Settings file /Users/g/.flowcept/settings.yaml was not found. You should either define the environment variable FLOWCEPT_SETTINGS_PATH with its path or install Flowcept's package to create the directory ~/.flowcept with the file in it.
A sample settings file is found in the 'resources' directory under the project's root path.

Obviously it's looking for a settings file in my home directory but the implementation of this is a poor user experience. The user should not be required to create such a file just to use the package. Some options to fix this are:

Have flowcept generate the file if it doesn't exist
Use default settings defined within the package if a settings file does not exist
