    <#
.SYNOPSIS
    Converts int32 values to uint32 values
.DESCRIPTION
    Converts int32 values to uint32 values. Useful for handling 32 bitmasks returned from some functions like Get-Acl
.PARAMETER Number
    An array of int32 values
.PARAMETER IncludeInput
    Switch to include the input in the output
.EXAMPLE
    Convert-Int32ToUint32 -Number -1610612736,-1 -IncludeInput
