/**
 * @brief This program helps construct an ir timing table for a air conditioner
 *
 * Each run of this program will generate a new table, for a specific mode and fan speed
 * It will iterate through all the temperature settings, and record the timing for each temperature
 * It will then print the timing table as a C++ 2D array, which can be copied into your main program
 * The first dimension is the temperature, the second dimension is the timing
