Rename functions

[hajdik]

Purpose

This PR renames functions as recommended in this issue. Wrappers were added so old function names redirect to new ones and raise a warning to the user.

Type of change

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (non-backwards-compatible fix or feature)
• Code style update (formatting, renaming)
• Refactoring (no functional changes, no API changes)
• Documentation update
• Maintenance update
• Other (please describe)

Testing

Old instances of names should no longer be present (excluding wrappers) and use of old names should raise a warning.
