A utility to get path info:
for example, a request uri could be:
/product/list.php/category/1/sort/price/asc

catetory: id=1
sort: "price", "asc"
PathInfoHelper is help to make this easier.

$helper->ScriptFile
##Get all path parameter string
$helper->ParameterString
for the example above, the result will be "/category/1/sort/price/asc"
##Get all path parameter array
same as ParameterString, but break them into an array
$helper->Parameters
##Get single parameter value if an parameter has only one value followed, get this single value.
$helper->getParameterValue($paramName)
for the example above, "/category/1"
$helper->getParameterValue("category") will returns "1"
##Get multi parameter value
if an parameter has more than one value, you can use getParameterValues method
$helper->getParameterValues($paramName, $valueCount)
for the example above, "/sort/price/asc"
$helper->getParameterValues("sort", 2) will returns array("price", "asc")
