/**
* Represents a string of text. Human readable language. This should be
* used any time you're dealing with actual text and not just binary
* data. If you neeed to transport raw binary data then consider using
* Blob and BlobBuilder.
*
* Text objects should be considered immutable. If you need to construct
* a Text object dynamically take a look at TextBuilder, and for
* serialization take a look at TextStream.
*
* A Text object is a sequence of Unicode code points. A code point is not
* one to one with a character. A single character can be represented with
* multilpe code points. In addition, a code point can also represent
* formatting or display inforamtion.
*
* Internally all data is stored in UTF-16, which is a fair compromise for
* mose text. All characters from all modern natural languages fit within
* the Basic Multilingual Plane, which requires only a single 16 bit value
* to represent it. However, when iterating through or addressing data
* in the Text object all work is done on a code point basis.
