-Cosmetic edits to Experimentalisp.hs
-Added changes to README.md file
-Pulled the global evironment and lisp_prim function into a separate file (so that we can easily make `apply`, `eval` and possibly `read` functions)
-Added :load command to the interpreter (EXTREMELY temporary; we really need to figure out a `load` primitive in the guest language, not fuck around with interpreter directives in the host languages)
-Musings on errors and modules
