BasisForAgeSelection Component

The BasisForAgeSelection component is used to select a time unit as the Basis for Age for a locality. If for some reason the component is used anywhere else in the app, it will need to be refactored since it's only designed to be used in the Age tab of a locality's edit view. The component is used by giving it

• a targetField which is the field in editData that the component should change (Required)
• a fraction which is used to calculate the minimum/maximum age of the locality (Required)
• a timeUnit value which is used together with the fraction to calculate the ages (Optional)
• a selectorTable which is used to select the time unit (Required)
• a disabled boolean value (Optional)

Whenever the user either selects a new time unit using the component, or the fraction value changes, the BasisForAgeSelection component calculates a new min/max age using and updates the editData with the new value. The currently selected time unit is saved in the currentBasisForAge state variable. When creating a new locality, this state variable will initially be undefined, but when editing an existing locality the state variable will first be set to the existing time unit (which is passed through the timeUnit argument to the component).

If disabled is set to true, the component cannot be clicked.
