 The repl has the following syntax (It's work in progress, new capabilities will be added)
-* simple arithmetic expressions: 
-  ** add, subtract, divide, multiply
-  ** variable declaration eg: a= ...
-  ** vector(x0,y0,x,y) adds a vector
-  ** remove(x) removes bindings (when it's an object (eg vector), removes it from the matrix)
-  ** method calls:
-  *** a = vector(0,0,12,1)
-  *** a.type()
-  *** > vector
-  ** property lookup
-  *** a.x
-  *** 12
