txattr_performance: Treatment attribute performance
In InnovationValueInitiative/IVI-NSCLC: The IVI-NSCLC model

Compute performance for multi criteria decision analysis (MCDA) criteria related to treatment attributes.

1 2	txattr_performance(struct, patients, econmod, treatments = iviNSCLC::treatments)

`struct`	A `model_structure` object.
`patients`	A data table returned from `create_patients`.
`econmod`	An economic model of class `"IndivCtstm"`. Disease progression must have been previously simulated (i.e., `$disprog_` cannot be `NULL`.)
`treatments`	An object in the same format as `treatments`.

A data.table with four columns:

sample: sample from econmod$disprog_
strategy_id: strategy_id from econmod$disprog_
route: Route of administration, weighted by the time each simulated patient uses each therapy in a treatment sequence. Oral administration is given a value of 1 and intravenous administration is given a value of 0.
yrs_since_approval: Years since FDA approval, weighted by the time each simulated patient uses each therapy in a treatment sequence.
