Checks and Balances

[TanyaS08]

There are still a few modifications that need to be made to make this project a bit more generalisable. This is two parts: I think we can write a series of tests to prompt users to structure their data correctly and possibly use types/struts to ensure consistency in data structure/naming.

In terms of checks needed:

• make sure that traits in feeding rules and trait data match up (both in terms of names and number)
• specify the taxon column name (allows us to more easily subset/differentiate a trait vector/column from the species one)
• find a way to standardise the feeding rules data frame structure - currently the internal names are very explicit and so we either need a helper function that allows users to turn their data frame into a 'feeding rules df' or find a way to make the function more general...

• Also check that all sub-traits within a broader trait category are represented
