Searcher module can be built from a config file and run search process easily, which can execute in local-mode（single-process） or distribute-mode（multi-process). During searching, the master process will cache intermediate results, and export and save the final best structure.

Searcher Class
__init__: Setup searching envirioment and then build strategy, sychonizer and population.run: Execute search loop and export the best structure info.search_loop: Master process collect and assgin newest population with workers and cache intermediate results. Then all processes execute search step.search_step: In search step, all processes pick a random structure info from population and then mutate a new structure info using strategy. If the new network meets the budget and has a high score, we will insert it to the population.export_cache_generation: cache the search intermediate population every log_freq .export_result: save and export best network structure info. -
Synchonizer Class
Sychonize population information between master and workers using mpi asynchronous communication.
