Packaged code for PyPI by nagannhh

[harshithn31]

##Issues Faced:
I was not able to import the package after installing it locally with pip.
I uploaded the package to TestPyPI but was not able to update it, as it was throwing an error. The detailed error is as shown below

Solutions tried:

1. Regenerated the API token and tried re-uploading.
2. Deleted the previously uploaded package completely and tried from scratch.
3. Changed the package name to avoid conflicts.

It is not immediately clear why the package uploading failed. One thing to try would be to use a single pyproject.toml to describe the packaging setup. Right now the setup instructions are distributed across many files, which is prone to error.
