Modular user experience

Tremor has been enhanced to support modular development with:

• A TREMOR_PATH environment variable to load multiple module paths
• Nestable modules via the mod clause in tremor-script and tremor-query
• Tremor-query specific - Modularise definitions of windows, operators and scripts.
  • https://docs.tremor.rs/tremor-script/modules/
  • https://docs.tremor.rs/tremor-script/pp/
  • https://docs.tremor.rs/tremor-script/functions/
• Tremor-script specific - Adds functional programming, allows modules defining constants and functions
  • https://docs.tremor.rs/tremor-query/modules/
  • https://docs.tremor.rs/tremor-script/pp/
• Both tremor-script and tremor-query can use modules via the use clause
• Modules may be nested in source or via the file system ( a directory is a module ) or a mix of both
• A preprocessor processes multiple modular sources into a single deployable artefact
