If you want to use the library in Micronaut application, the library registers a bean of type
groovycalamari.eurorates.EuroRatesApi in the Micronaut’s application context.
You can use the library without a Micronaut Application Context. In that case, to obtain a
EuroRatesApi euroRatesApi = new ManualEuroRatesApi();
The api contains methods to obtain the current rates, historic rates and last 90 days rates.
