-// | Special note concerning code documentation:                          |
-// | QuerySim was originally created for use during development of        |
-// | applications built using the Fusebox framework. (www.fusebox.org)    |
-// | Fusebox uses an XML style of documentation called Fusedoc. (Which    |
-// | is admittedly not well suited to documenting classes and functions.  |
-// | This short-coming is being addressed by the Fusebox community.) PEAR |
-// | uses a Javadoc style of documentation called PHPDoc. (www.phpdoc.de) |
-// | Since this class extension spans two groups of users, it is asked    |
-// | that the members of each respect the documentation standard of the   |
-// | other.  So it is a further requirement that both documentation       |
-// | standards be included and maintained. If assistance is required      |
-// | please contact Alan Richmond.                                        |

-            Extensive revision that is backwardly compatible but eliminates the
-            need for a separate .sim file.
-        </history>
-        <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Create" date="10-July-2002">
-            Rewrote in PHP as an extention to the PEAR DB API.
-            Functions supported:
-                connect, disconnect, query, fetchRow, freeResult,
-                numCols, numRows, getSpecialQuery
-            David Huyck (bombusbee.com) added ability to escape special
-                characters (i.e., delimiters) using a '\'.
-            Extended PEAR DB options[] for adding incoming parameters.  Added
-                options:  columnDelim, dataDelim, eolDelim
-        </history>
-        <history author="David Huyck" email="b@bombusbee.com" type="Update" date="19-July-2002">
-            Added the ability to set the QuerySim options at runtime.
-            Default options are:
-                'columnDelim' => ',',            // Commas split the column names
-                'dataDelim'   => '|',            // Pipes split the data fields
-                'eolDelim'    => chr(13).chr(10) // Carriage returns split the
-                                                 // lines of data
-            Affected functions are:
-                DB_querysim():          set the default options when the
-                                        constructor method is called
-                _parseQuerySim($query): altered the parsing of lines, column
-                                        names, and data fields
-                _empty2null:            altered the way this function is called
-                                        to simplify calling it
-        </history>
-        <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="24-July-2002">
-            Added error catching for malformed QuerySim text.
-            Bug fix _empty2null():  altered version was returning unmodified
-                                    lineData.
-            Cleanup:
-                PEAR compliant formatting, finished PHPDocs and added 'out' to
-                Fusedoc 'io'.
-                Broke up _parseQuerySim() into _buildResult() and _parseOnDelim()
-                to containerize duplicate parse code.
-        </history>
-        <history author="David Huyck" email="b@bombusbee.com" type="Update" date="25-July-2002">
-            Edited the _buildResult() and _parseOnDelim() functions to improve
-            reliability of special character escaping.
-            Re-introduced a custom setOption() method to throw an error when a
-            person tries to set one of the delimiters to '\'.
-        </history>
-        <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="27-July-2002">
-            Added '/' delimiter param to preg_quote() in _empty2null() and
-            _parseOnDelim() so '/' can be used as a delimiter.
-            Added error check for columnDelim == eolDelim or dataDelim == eolDelim.
-            Renamed some variables for consistancy.
-        </history>
-        <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="30-July-2002">
-            Removed protected function _empty2null().  Turns out preg_split()
-            deals with empty elemants by making them zero length strings, just
-            what they ended up being anyway.  This should speed things up a little.
-            Affected functions:
-                _parseOnDelim()     perform trim on line here, instead of in
-                                    _empty2null().
-                _buildResult()      remove call to _empty2null().
-                _empty2null()       removed function.
-        </history>
-        <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="1-Jan-2003">
-            Ported to PEAR MDB2.
-            Methods supported:
-                connect, query, getColumnNames, numCols, valid, fetch,
-                numRows, free, fetchRow, nextResult, setLimit
-                (inherited).
-        </history>
-        <history
-            Removed array_change_key_case() work around for <4.2.0 in
-            getColumnNames(), found it already done in MDB2/Common.php.
-        </history>
-        <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="3-Feb-2003">
-            Changed default eolDelim to a *nix file eol, since we're trimming
-            the result anyway, it makes no difference for Windows.  Now only
-            Mac file eols should need to be set (and other kinds of chars).
-        </history>
-        <note author="Alan Richmond">
-            Got WAY too long.  See querysim_readme.txt for instructions and some
-            examples.
-            io section only documents elements of DB_result that DB_querysim uses,
-            adds or changes; see MDB2 and MDB2_Driver_Common for more info.
-            io section uses some elements that are not Fusedoc 2.0 compliant:
-            object and resource.
