<#
 # This function will provide a virtual object, containing an array
 # of Performance Counters. The object has the following members:
 # Name
 # Value
 # This will ensure we will not have to worry about looping an array
 # of mutltiple instances within a counter handler, because this
 # function will deal with everything, returning an hashtable
 # containing the parent counter name including the values and
 # samples for every single instance
