Ignore test case feature

Added the ignoring test case feature, which is supposed to be used when you added couples of test cases.
Imagine your code passed first test case, but didn't the second one. For the debugging sake, you'd like to ignore the first test case when running run sub command, so you can keep your standard output as clean as possible.

Add @cpg_test_ignored annotation in the beginning of a test case's input file, which you'd like to ignore when running run sub command.

Below formats are allowed:

(These annotations must be put in input file, not output file）

// @cpg_test_ignored

/** @cpg_test_ignored */

/* @cpg_test_ignored */

/** @cpg_test_ignored 
*/

/*
@cpg_test_ignored 
*/

/* Input File Title
@cpg_test_ignored 
*/
