Struct GChart 

pub struct GChart {
    pub g_bar: f64,
    pub points: Vec<GChartPoint>,
}

G chart (geometric distribution) result for rare-event monitoring.

Monitors the number of conforming units between consecutive defect events. Appropriate when the defect rate is very low (< 1%) and standard P/NP charts produce degenerate limits.
