# About
This package provides utilities for designing and analyzing truss structures

# Usage
Here are some basic examples of usage
## Building a truss
For example, you can build a truss with something like:
```rust
use trussx::{Truss, point};
let mut x = Truss::new();
let a = x.add_joint(point(0.0, 0.0, 0.0));
let b = x.add_joint(point(3.0, 0.0, 0.0));
let c = x.add_joint(point(1.5, 1.5, 0.0));
let _ab = x.add_edge(a, b);
let _bc = x.add_edge(b, c);
let _ac = x.add_edge(a, c);
```
