- Store the variable names associated with the columns of a table. - Time dependencies are still handled in the same way as before. However, we now also have the option to model a dependency on the X coordinate. The former is updated for each solution step, whereas the latter is evaluated just once before the solution loop. - Removed the explicitly defined copy assignment operator and copy constructor of class `Table` since it was identical to what the compiler would generate. Also use compiler-generated default constructors and destructors. - Replaced some explicit type names by `auto`. - Several minor layout improvements.
The test carries out two checks: 1. Whether the sum of the vertical reaction forces equals the total vertical load due to the non-uniform line load. 2. Whether the applied vertical line load per top node matches our expectations (it mimics the load imposed by an embankment). Furthermore, helper function `get_nodal_variable` now accepts an optional list of node IDs, to only retrieve the solution step values for those nodes. By default, it returns the values of all nodes in the model part of the first output process, just like it used to be.

- The applied non-uniform line load has been given a small offset to make the model asymmetric. The expected applied line load values have been updated accordingly. - Added a `README` file that gives a brief description of the new test. It also shows how the total vertical load has been calculated.

- Explained in somewhat more detail in the `README` file how to
calculate the total applied load.
- Throw an exception when an unknown table variable is supplied to
`ApplyComponentTableProcess::ExecuteInitialize`.
- Removed a redundant blank line from the `README` file (found by
Codacy).
- Added a missing code language flag ('text') to the `README` file
(found by Codacy).

📝 Description
This PR adds support for applying non-uniform line loads. It does so by attaching a table to a uniform line load, where the table defines the relationship between a set of X coordinates and the corresponding "pressure" values. The pressures applied to nodes will be linearly interpolated (and/or linearly extrapolated, if needed) using this table.
