compute: Compute Metrics

Description

Metric object is not evaluated until compute() method is called on it. Method would display calculation progress and would use Metric object's disk cache to store any computational results obtained in the process.

Usage

compute(...)

Arguments

...

One or multiple objects of class Metric.
