Variables retrieved from the DebugService should use proper '$' notation #29
Description
This issue causes top-level variables retrieved from the DebugService to not have the dollar sign '$' prefix, causing some confusion when they are seen in a debugger client. The fix will cause the dollar sign prefix to be introduced to top-level variables, i.e. those that are obtained from calling "Get-Variable". Children of those top-level variables do not need this prefix.
