Multiple issues fixed.

- Variable use before assignment
- Unhandled edge cases where variables referenced may not have the subdata/indexes requested
- try/catch fixes where 'finally' references a variable that might not exist
- Unnecessary imports
- Added requirements.txt file with base module requirements (without version specificity at this time)
