/**
 * <h1>ERXQueryAttributes.java</h1>
 * 
 * <p style="max-width:700px">
 * A convenient subclass of NSMutableArray<EOAttribute> to make it easy to create multiple
 * ad hoc attributes that can be used with ERXQuery.  It uses a fluent style API so that
 * it can be used like this:
 * <pre>
 * {@code
 * NSArray<EOAttribute> attributes =
 *     ERXQueryAttributes.create(claimEntity)
 *         .add("providerFullName", "provider.fullName", "varchar50")
 *         .add("claimCount", "COUNT(DISTINCT claimID)", "intNumber");
 * }
 * </pre>
