Title: Modify the config parser to use symbolized key and group names

When I parsed a configuration file, the hash keys and group names where represented as string.
example:
```ruby
{
"foo" => "bar",
"baz" => "quux",
"123" => "456"
}
```

But, I think it will be much more convenient to deal with symbols in that case rather than strings.
example:
```ruby
{
:foo => "bar",
:baz => "quux",
:"123" => "456"
}

Also, I have modified the ability to add value and add group to support the above behavior.

I have added tests for add value and add group behavior and all the tests are passing.
