Idiom #139 Create temp directory

Create a new temporary folder on filesystem, for writing.

Code 
string mkTmpDir()
{
    import std.uuid, std.file, std.path;
    string d = tempDir ~ dirSeparator ~ randomUUID.toString;
    if (!d.exists)
    {
        mkdir(d);

The standard library doesn't provide a function for that.
mkTmpDir generates a folder in the temp dir that takes a UUID as name. THe function succeeds when a non empty string is returned.
