/*********************************************************************************************************************\
* LAST UPDATE
* ============
* March 22, 2007
*
*
* AUTHOR
* =============
* Kwaku Otchere
* ospinto@hotmail.com
*
* Thanks to Andrew Hewitt (rudebwoy@hotmail.com) for the idea and suggestion
*
* All the credit goes to ColdFusion's brilliant cfdump tag
* Hope the next version of PHP can implement this or have something similar
* I love PHP, but var_dump BLOWS!!!
*
* FOR DOCUMENTATION AND MORE EXAMPLES: VISIT http://dbug.ospinto.com
*
*
* PURPOSE
* =============
* Dumps/Displays the contents of a variable in a colored tabular format
* Based on the idea, javascript and css code of Macromedia's ColdFusion cfdump tag
* A much better presentation of a variable's contents than PHP's var_dump and print_r functions
*
*
* USAGE
* =============
* new dBug ( variable [,forceType] );
* example:
* new dBug ( $myVariable );
*
*
* if the optional "forceType" string is given, the variable supplied to the
* function is forced to have that forceType type.
* example: new dBug( $myVariable , "array" );
* will force $myVariable to be treated and dumped as an array type,
* even though it might originally have been a string type, etc.
*
* NOTE!
* ==============
* forceType is REQUIRED for dumping an xml string or xml file
* new dBug ( $strXml, "xml" );
*
