要件を満たさない場合は例外を発生させます

``var nameCheck = require('cocotte-name');

nameCheck('abc'); // pass nameCheck('123'); // throw error nameCheck('ab_c'); // pass nameCheck('ab_'); // throw error nameCheck(''); // throw error nameCheck('abcdefghijabcdefghijabcdefghijabcdefghij'); // throw error nameCheck('if'); // throw error; nameCheck('window'); // throw error; nameCheck('undefined'); // throw error;`
