/**
 * Implementation of Mathematica symbols which are probably the most important elements of a parse tree. Symbols in
 * Mathematica are not only the variables you use. Due to the <em>data is code</em> paradigm of Mathematica, even the
 * functions you call like <code>Sqrt[2]</code> are expression having a symbol as head (the <code>Sqrt</code>).
 * <p/>
 * Symbols with explicit context like <code>Developer`ToPackedArray</code> are parsed as one symbol and this class
 * provides methods to separate the parts.
