Creates an instance of {@link Mapper}, with all the configuration set to its default values.
<p>
The only special handling is for mapping file. If there is a file with name {@code dozerBeanMapping.xml}
available on classpath, this file will be used by created mapper. Otherwise the mapper is implicit.

@return new instance of {@link Mapper} with default configuration and optionally initiated mapping file.
