Description

The upper and lower Stream Evaluators will convert strings to upper and lower case. The trim Stream Evaluator will trim whitespace from strings and the split Stream Evaluator will split a string by a delimiter regex.

These functions will operate on both strings and lists of strings. These are useful functions for cleaning data during the loading process.
