Some common simple tool for proc-macro impl

What can do:

• Quickly create processors in the style of #foo(...)
• Common methods, such as add, split_puncts, is_ident, as_ident, into_punct, is_joint, as_punct_char and set_spaned etc
• ParseIter, can peek n, and peek jointed puncts

Functions

err

Make compile_error! {"..."}
