Find a function or method matching a given name within certain bounds.

@param Tokens $tokens     the Tokens instance
@param string $name       the function/Method name
@param int    $startIndex the search start index
@param int    $endIndex   the search end index

@return null|array An associative array, if a match is found:

- nameIndex (int): The index of the function/method name.
- startIndex (int): The index of the function/method start.
- endIndex (int): The index of the function/method end.
- bodyIndex (int): The index of the function/method body.
- modifiers (array): The modifiers as array keys and their index as
the values, e.g. array(T_PUBLIC => 10)
