defining and calling functions about rimu HOT 3 CLOSED

okay i tried https://github.com/ahdinosaur/rimu/tree/functions but nah

new plan sketch:

1. rimu-expr

• define Expression

2. rimu-value

• define Function
  • Function is struct with "name" (String), "args" (Vec<String>) "body" (Expression)

3. rimu-env

• defines Environment (previously Context)

4. rimu-expr-parse

• parse String to Expression

2. rimu-expr-eval

• evaluates Expression (with Environment) to Value

6. rimu

from rimu.

a side thought, is if Expression ends up being fully featured, then a Block (previously Operation) could end up just returning the Expression that represents itself, a Template could return the Expression that represents itself.
