## Production control

Control Module - Production - Common functions used to track production of items

### Usage

        -- import the module from the control modules
        local Production = require 'modules.control.production' --- @dep modules.control.production

        -- This will return the less precise index from the one given
        -- this means that one_second will return one_minute or ten_hours will return fifty_hours
        -- the other precision work like wise
        Production.precision_up(defines.flow_precision_index.one_second)

        -- The get production function is used to get production, consumion and net
        -- it may be used for any item and with any precision level, use total for total
        Production.get_production(game.forces.player,'iron-plate',defines.flow_precision_index.one_minute)

        -- The fluctuations works by compearing recent production with the average over time
        -- again any precision may be used, apart from one_thousand_hours as there would be no valid average
        Production.get_fluctuations(game.forces.player,'iron-plate',defines.flow_precision_index.one_minute)

        -- ETA is calculated based on what function you use but all share a similar method
        -- for production eta it will take current production average given by the precision
        -- and work out how many ticks it will require to make the required amount (1000 by default)
        Production.get_production_eta(game.forces.player,'iron-plate',defines.flow_precision_index.one_minute,250000)

        -- Both get_color and format_number are helper functions to help format production stats
        -- get_color will return green,orange,red,or grey based on the active_value
        -- the passive_value is used when active_value is 0 and can only return orange,red,or grey
        Production.get_color(clamp,active_value,passive_value)

### Dependencies

### Formating

get_color(clamp, active_value, passive_value) | Returns a color value bassed on the value that was given
format_number(value) | Returns three parts used to format a number

### Precision

precision_up(precision) | Gets the next lesser precision index value, eg 1 second -> 1 minute
precision_down(precision) | Gets the next greater precision index value, eg 1 minute -> 1 second
precision_ticks(precision) | Gets the number of tick that precision is given over, eg 1 minute -> 60 ticks

### Statistics

get_production_total(force, item_name) | Returns the production data for the whole game time
get_production(force, item_name, precision) | Returns the production data for the given precision game time
get_fluctuations(force, item_name, precision) | Returns the current fluctuation from the average
get_production_eta(force, item_name, precision[, required=1000]) | Returns the amount of ticks required to produce a certain amount
get_consumsion_eta(force, item_name, precision[, required=1000]) | Returns the amount of ticks required to consume a certain amount
get_net_eta(force, item_name, precision[, required=1000]) | Returns the amount of ticks required to produce but not consume a certain amount
