import is a Mini Micro function that loads a MiniScript file from the current
directory, /sys/lib, /usr/lib, or some path defined in
import looks for a file with the module name plus ".ms".
Any values defined by that code then become available in a map of the same name.
The following example loads a script called "mathUtil.ms" (normally found in /sys/lib), and makes it available as a map called
import "mathUtil" print mathUtil.radToDeg(2*pi) // prints 360
Some modules, like listUtil, stringUtil, and mapUtil, extend these built-in types with new methods. For example, the built-in list type does not have a .reverse method, but it does once you import "listUtil":
import "listUtil" print [1,2,3].reverse // prints [3, 2, 1]
