/**

 * Wraps a {@link SchemaBuilder} and does all the semantic checks

 * <h2>Usage</h2>

 * <p>

 * Whereas you normally write it as follows:

 * <pre>

 * YourParsedPattern r = (YourParsedPattern)parseable.parse(sb);

 * </pre>

 * write this as follows:

 * <pre>

 * YourParsedPattern r = (YourParsedPattern)parseable.parse(new CheckingSchemaBuilder(sb,eh));

 * </pre>

 *

 * <p>

 * The checking is done by using the {@code rngom.binary} package, so if you are using

 * that package for parsing schemas, then there's no need to use this.
