Rebrand to Galaxy, major improvements to Bedrock support, still needs some TLC though

+//! This module defines CharOrStr, a wrapper struct to deal with cases where we can have either a
+//! char or a string. For example, this is used for Cells in Grids where we can have either just a char
+//! (normal case) or a String (when we have zerowidth characters in a Cell). This structure helps abstract
+//! away a clean API for dealing with both cases.
