I've thinking about the possibility of extending this package to be able to perform Vector/Tensor calculus operations.
A suitable discretization of a vector field is an `Array{SVector{N, T},N}`.

There is a lot of new finite difference functions (not one liners) required for the adjoint TTI. You can see it in the new notebook. Do you think we want to keep the s…

The following comes from a doctest in `src/sage/calculus/riemann.pyx`:
Sage 5.12:
```
sage: f(t) = e^(I*t) - 0.5*e^(-I*t)
sage: fprime(t) = I*e^(I*t) + 0.5*I*e^(-I*t)
sage: m = Riemann_Map([f], [f…

I have found the following bug in limit:
```
sage: version()
'SageMath version 8.6, Release Date: 2019-01-15'
sage: f=exp(-2*x^2)-cos(2*x);f
-cos(2*x) + e^(-2*x^2)
sage: g=x*(sin(x))^3;g
x*sin(x)^3…

int16_t ReadGyroAngle(int gyro_direct_fd)
{
int16_t val;
if(lseek(gyro_direct_fd, 0x42, SEEK_SET)==-1)
Die("lseek(gyro_direct_fd, 0x…
