Based on `pybind11`, I created a Python module in C++. Possible minor changes and enhancements can be expected.

This module contains:

- A function returning the n-th element of the Fibonacci sequence.

- A function that returns numerical solution of the given ordinary differential equation (ODE) of order `k`:

   - `x^{k}(t) = f(t, x(t),..., x^{k-1}(t))`

   - `x(t_{0}) = x_{0}`

   - `x'(t_{0}) = x'_{0}`

   - ...

   - `x^{k-1}(t_{0}) = x^{k-1}_{0}`

- A function returning a set of points `(x, y, z)` such that `F(x, y, z) = 0` within provided bounds to each of variables `x, y, z` with provided error tolerance, nods granularity, and number of threads

  employed to find desired solution. Function uses string evaluation based on `exprtk.hpp` (see: https://www.partow.net/programming/exprtk/index.html ). 

- **Vector class:** This class is a 1-dimensional  C++ container for template type data. Based on Vector class there is created a class Vector_d which is Python embedding of `Vector`. Below is a list of functionalities available in the C++ class:

  - **Template:**

    - Default constructor

    - Constructor depending on the size of the Vector

    - Constructor based on the size of the Vector and a given coordinate

    - Constructor based on the `std::vector` data container

    - Constructor based on the object Vector

    - Destructor

  - **Operators:**

    - Assignation `=`

    - Comparison `==`

    - Addition `+`

    - Coordinate-wise multiplication `*`

    - Multiplication by scalar `*`

    - Inner product operator `^`

    - Input stream `>>`

    - Output stream `<<`

  - Insertion and appendation

  - Removal of coordinate by index or by value

  - Merge of two Vectors

  - Type conversion

  - Action of an external function in a given rolling window on Vector's coordinate

  - Sorting

  - Action of an external function on rows of several Vectors

  - Getting length and coordinate value by index

  - Iteration functionality (for Python usage only)

  - Modification of chosen coordinate

  - Returning of indices with provided values

  - Verification if a Vector has a given value stored in coords
