adding the size of child directories to the directory that contains them.

## If they specify the -IncludeSubdirectories flag, then we want to account
## for all subdirectories in the size of each directory
if($includeSubdirectories)

Get-ChildItem | Where-Object { $_.PsIsContainer } |
Select-Object Name,
@{ Name="Size";
Expression={ ($_ | Get-ChildItem -Recurse |
Measure-Object -Sum Length).Sum + 0 } }
}
## Otherwise, we just find all directories below the current directory,
## and determine their size
