`min`

Determines the smallest value in a list (or null if the list is empty).

The list can contain any type of comparable object, including (but not limited to):

Number;
String; and
curam.util.type.Date.

Note: All instances of Number are converted to CER's own numerical format (backed by java.math.BigDecimal) before comparison.
