 ## Usage
+Command line arguments with no dashes are the base class(es) or attribute(s). Each dash represents another 'level'. In this example, person is the base class, firstname, lastname, and age are the attributes, and john, smith, and 30 are the values of those attributes.
+
+Levels are determined by the number of dashes before an argument. The fewer dashes the higher the level. Arguments with no levels below them (they have no arguments with more dashes following them in the list) are values. Arguments with only one level after them are attributes. Arguments with multiple levels after them are classes.
