More database functions

db has its own limits when it comes to getting datasets with a specific name. To get a list of the datasets with a specific name, you can use the model DAO. Each model has its own model DAO: ProcessDao, FlowDao, ProductSystemDao, etc.

DAO can be used with the following methods:

• ModelDao(db).getForName(name) gets all the datasets with the name name
• ModelDao(db).getAll() gets all the datasets
• ModelDao(db).deleteAll() deletes all the datasets (use with caution)

For example, to get all the processes with the name Aluminium smelting:

processes = ProcessDao(db).getForName('Aluminium smelting')
