/**
* clauseExplode
*
* explodes a string into array using custom brackets and

*
* example:
*
* parameters:
* $str = "(age < 20 AND age > 18) AND name LIKE 'John Doe'"
* $d = ' '
* $e1 = '('
* $e2 = ')'
*
* would return an array:
* array('(age < 20 AND age > 18)',
* 'name',
* 'LIKE',
* 'John Doe')
*
* @param string $str
* @param string $d the delimeter which explodes the string
* @param string $e1 the first bracket, usually '('
* @param string $e2 the second bracket, usually ')'
*
* @return array
