new syntax

q.k: q.txt
has been updated to the new syntax.
the test case runs fine, but not all functions are tested.
op might be wrong. i don't know how that's supposed to be called.
dyadic versions of scan and over are gone and need to be rewritten.
x+/y is often +/x,y or +/(,x),y. seeded scan is e.g. 1_+/(,x),y

also basis:{,'/'$(+sz[x]\\nzpos x)} should probably be sz[]\nzpos x
encode/decode use single slashes now.
