Subject: Started work on Text and friends.

Text processing isn't trivial, and I want this iteration to be
significantly more robust.  This time I/O will be seperated out into
codecs that will handle the encoding/decoding to/from different formats.

+     * 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.
