7b0435d3ec Separated parsing into two phases 
The first phase (parser.rs) is generally context-free, and builds a
naive AST where for example function calls are parsed as `f*(x)` where
`f` is a variable and `(x)`is a group. The second phase (analysis.rs)
then creates a new AST, where these are turned into a function call
expression instead.
