====== IR-ELLI-DISPATCHER ======

Package ''ELLI'' contains 2 self-evaluating symbols ''RAE'' and ''RCE''.
They are used in following function:

''CONFIG''

Takes zero or one arguments. With zero arguments it just returns the symbol representing the cofiguration. One argument that can be supplied must be one of the symbols ''RAE'' or ''RCE''. The IrElliSoft configuration variable controls the formatting of the output .big files.

<code lisp>
>(elli::config 'elli::rae)  
ELLI::RAE

>(elli::config elli::rce)  ; self-evaluating symbol also works
ELLI::RCE
</code>

''INFO''

Takes one argument that must be string. Sends the string to the main application window log text. Can be used for reporting progress of the Lisp script to the user. Returns the string.

<code lisp>
>(elli::info "Hello, World!")
"Hello, World!"   ; this is now printed on the main window
</code>

''APPEND-LABEL''

Takes one argument that must be string, or NIL. Temporarily adds the string to the sample/experiment label.
Empty string or NIL erases the temporary appendix. Is used in scripts performing measurements with/without compensator. Returns the full sample/experiment label with the appendix.

<code lisp>
>(elli::append-label " with SiComp")
"YBCO film on LAO with SiComp"

>(elli::append-label NIL)
"YBCO film on LAO"
