/**
 * ## About
 *
 * Code preamble is a short code snippet adding to the beginning of the program. A typical one is:
 *
 *
 * ```
 * #include <iostream>
 * using namespace std;
 * ```
 *
 * This feature is useful. Maybe inserting header files is interesting for the first several times,
 * it is dreadful if we need to add tons of it each time we do the problems, especially for a dreadful
 * language like C/C++
 *
 * ## Configuration
 *
 * To add a preamble for one language, the user will follow this schema:
 *
 * ```
 * "leetcode.language.preamble" = {
 *      "cpp" : "#include <iostream>",
 * }
 * ```
 *
 * @param language
