fit_data(model, tdata, ydata, p0)

Fit the model function `model` to the data `ydata` at time points `tdata`
using initial parameters `p0`.

# Arguments
- `model::Function`: The model function to fit.
- `tdata::Vector`: A vector of time points.
- `ydata::Vector`: A vector of corresponding data points.

"""
# Convert a vector of vectors to an array
This function assumes that each vector is the same length;
i.e.
v1 = [ [1,2], [2,3], [5,6] ] # this is fine
v2 = [ [1,2,8], [2,3], [5,6] ] # this is not fine

Example of usage:
```
vv = [[1,2,3], [4,5,6], [7,8,9],[12,13,14]]
