Detailed Description

SExpressionReader provides a reader for OpenLists and atoms. In addition to tokenizing for atoms of specific types: Doubles, Longs, and Strings (which are interned as Symbols), an entire OpenList can be read by a single method call, assuming the input is in the form of an S expression. In an S expression, the elements of a OpenLists are shown in parentheses with a space between each element. (The elements can themselves be S expressions representing OpenLists.)
