Overview
Our text spinner class really doesn’t like handling the TranslatedString or Untranslated classes returned by the R18n library. So instead we return these TextWrapper instances which have dynamically defined methods corresponding to the known structure of the R18n text file. Most importantly, if a user has accessed a leaf node in the code we return a regular String instead of the R18n classes.

Dynamic Method Handling
This class handles dynamic methods through the method_missing method
#method_missing(name, *args) ⇒ Object
