The experimental Groovy scripts has several issues that should be resolved by re-factoring it:

1. Turn the variables defined in the top of the file into constants with upper case manes to ensure they're not used in functions by mistake

2. Remove unused arguments from functions

3. Move the main() function definition to the top of the file so its easier to quickly see an overview of the whole flow

4. Use the "global" constants inside main() instead of passing gazillion parameters to it.

5. Pass parameters directly to function instead of turning them into strings and using interpolation

6. Use 'for-each' loops instead of C-style indexed loops.

7. Use consistent indention throughout the file
