By default "import" brings in class definitions, not the members of the 
class.  So

   import helperClasses.rType;

would import the class, and you'd have to use

   rType.isBetween( x, y, z);

C.f. that link Peter gave you, which uses this style of static method 
access.  "Import static" is a special import syntax that imports only 
the static members of rType, not the class definition, so that you can 
use its static methods and fields "bare," without a class name as a 
qualifier.  It's a convenience for typing (and reading), nothing else.
