Cirru Parser

This tiny parser parses indentation based syntax into nested a vector, then it could used as S-Expressions for evaluation or codegen.

defn fib (x)
if (<= x 2) 1
+
fib $ dec x
fib $ - x 2

parses to:

[ ["defn" "fib" [ "x" ]
[ "if" [ "<=" "x" "2" ] "1"
[ "+" [ "fib" ["dec" "x"] ] [ "fib" ["-" "x" "2"] ] ]
]
] ]
