Creating LCAScope Objects for different database requirements

[mchaf]

For the LCAScope method, we currently use it to create database fields for our own tabulation and data visualization. As we begin to submit to various databases (SE2050, or EC3, for example), we're going to need to adhere to the respective databases' data fields. Should we create new LCAScope methods for each type of database?

Let me know if this needs further explaining!
