/**
*   function:   this is the constructor to the XMLP Object
*   Author:   Scott Severtson
*   Description:XMLP is a pull-based parser. The calling application passes in a XML string
*   to the constructor, then repeatedly calls .next() to parse the next segment.
*   .next() returns a flag indicating what type of segment was found, and stores
*   data temporarily in couple member variables (name, content, array of
*   attributes), which can be accessed by several .get____() methods.
*
*   Basically, XMLP is the lowest common denominator parser - an very simple
*   API which other wrappers can be built against.
