docs: Utility method to derive a setter/getter method name from a property name, where the
  prefix is typically "set" or "get" and the first letter of the property name is
  capitalized.
  
  @param prefix The precursor to the method name, before the property name begins, typically
  "set" or "get".
  @param propertyName The name of the property that represents the bulk of the method name
  after the prefix. The first letter of this word will be capitalized in the resulting
  method name.
  @return String the property name converted to a method name according to the conventions
  specified above.
