BootConfig provides a hierarchical declaration syntax for keys:
```
foo.bar {
baz.fooz {
....
}
}
```
Each Node in the path, is a step taken into a nested scope. In order to resolve
a key, the entire path must be taken into account. Elements in the path are joined by '.'.
When a node is visited, it is provided the current path, through this means visitors/observer
patterns may skip entire subtrees.
Public Methods
bool start_of (std::string_view key)The key parts in `key` form a key prefix of this.
E.g.:
```
Key key = ["foo.bar"]
a.prefix_of("foo.bar.baz") is true.
```

bool starts_with (std::string_view key)The key parts in this form a key prefix of `key`.
E.g.:
```
Key key = ["foo.bar"]
a.starts_with("foo") is true.

CompareResult Compare (std::string_view key)Returns the relationship between the `ley` and the path to the current.

Enumerations
enum CompareResult| Name | Value |
|---|---|
| kParent | 0 |
| kChild | 1 |
| kMatch | 2 |
| kNoMatch | 3 |
Result information obtained when comparing abn arbitrary key in string form against a Key.
Caller then may take actions based on this.
A Key can be thought of a collection of string joined by '.'. We will call each of the elements
in this collection as a section of a key. The unit of comparison is per section.For example,
guven two keys a("foo.bar") and b("foo.barz"), even though a is a prefix of b, since the
sections 'bar' and 'barz' do not match, the result is considered `kNoMatch`.
