TOML tables are dictionaries where lookups are done using string keys. In
general, all access methods on tables are named `toml_*_in(...)`.
Keys in tables can be interrogated using an integer index:
```c
toml_table_t* tab = toml_parse_file(...);
for (int i = 0; ; i++) {
const char* key = toml_key_in(tab, i);
if (!key) break;
printf("key %d: %s\n", i, key);
}
```
Once you know a key and its content type, retrievals can be done with one of these methods:
In the normal case, you know the key and its content type, and retrievals can be done
using one of these functions:

toml_string_in(tab, key);

#### Accessing Array Content
TOML arrays can be deref-ed using integer values. In general, all access methods on arrays are named `toml_*_at()`.
