Computed columns with variable number of tasks

[ckcollab]

Columns are computed against KNOWN columns, i.e....

Column: Average scores
Key: "avg_scores"
Computation: "avg"
Computation against: ["set1_score", "set2_score"]

Column: Set 1 score
Key: "set1_score"

Column: Set 2 score
Key: "set2_score"

We want to refactor "computations" to be against columns dynamically

Column: Average scores
Key: "avg_scores"
Computation: "avg"
Computation against **search:** any column containing "_score"

Column: Set 1 score
Key: "set1_score"

Column: Set 2 score
Key: "set2_score"

This new style would work dynamically as new columns are added.
