 * SQLStatementCountValidator - Validates recorded statements count.
 *
 * First you execute some operations against your database and then you check how many statements were executed.
 * This is a useful tool against the "N+1" problem or suboptimal DML statements.
 *
 * 
 * For more details about how to use it, check out this article on vladmihalcea.com.
