Changes in Mini-XML 0.93

• New mxmldoc example program that is also used to create and update code documentation using XML and produce HTML reference pages.
• Added mxmlAdd() and mxmlRemove() functions to add and remove nodes from a tree. This provides more flexibility over where the nodes are inserted and allows nodes to be moved within the tree as needed.
• mxmlLoadFile() now correctly handles comments.
• mxmlLoadFile() now supports the required "gt", "quot", and "nbsp" character entities.
• mxmlSaveFile() now uses newlines as whitespace when valid to do so.
• mxmlFindElement() now also takes attribute name and attribute value string arguments to limit the search to specific elements with attributes and/or values.
NULL pointers can be used as "wildcards".
• Added uninstall target to makefile, and auto-reconfig if Makefile.in or configure.in are changed.
• mxmlFindElement(), mxmlWalkNext(), and mxmlWalkPrev() now all provide "descend" arguments to control whether they descend into child nodes in the tree.
• Fixed some whitespace issues in mxmlLoadFile().
• Fixed Unicode output and whitespace issues in mxmlSaveFile().
• mxmlSaveFile() now supports a whitespace callback to provide more human-readable XML output under program control.
