Datacost

**Changes Since the Last Release**

- datacost.py is now included in the root directory. This has been tested locally to allows users to import datacost by writing 'import datacost'.

**Changes Since Last Release**

- Changed the package name to 'dc1' to represent datacost version1. This means that users import datacost by writing 'from dc1 import datacost'.

**Changes Since Last Release**

Fixed a problem which caused users to lack the ability to import the module.

**Changes Since Last Release**

Due to an error in the setup.py file, the module was being setup as a package. This meant that one would have to write 'import datacost.datacost' to import the module. This has been fixed so that users can write 'import datacost'.

**Changes Since Last Release**

Last release claimed to have fixed a bug for module imports. However, the imports were still not being performed as expected. The module name was incorrect and could only be imported after installation by 'import src'. This has been fixed and should now be able to import correctly using 'import datacost'.

**Changes Since Last Release**

- Fixed a critical error where users could not import the module.
