v5.0.0 database

v5.0.0 adds a database to the data directory as database.yml. It stores all ran simulations and reuses them (if they were run with enough iterations) instead of simulating again.

By default the database is enabled. Options to change the behavior are listed below:

• no-db-write database will not be written to disk again at the end.
• no-db-load database is not loaded from the dist. The database fresh computed database will replace existing database.yml.
• no-db disables write and load operation
• strict-db tuo aborts if the database is either from a different tuo version or from different xml files.
• db-limit N lets you specify the amount (N) of simulations to be stored in the database (default is infinite).
