 * Class representing the fully qualified name of a class, method or field.

 *

 * This tool reads a multitude of input formats all of which represents the fully qualified path to

 * a Java symbol slightly differently. To keep things consistent, all parsed APIs are converted to

 * Symbols.

 *

 * All parts of the fully qualified name of the Symbol are separated by a dot, e.g.:

 * <pre>

 *   package.class.inner-class.field
