Exemple of text graphs

This is the output of **blc_core/t_array** see the [code]( https://framagit.org/blaar/blc_core/blob/master/t_array/main.cpp) and the [cmake config file](https://framagit.org/blaar/blc_core/blob/master/t_array/CMakeLists.txt)
### Manipulating **blc_array** vector

You can modify the code to dynamically refresh the graph with something like:
```c++
...
//We display 100 times the graph with the sinusoid shifted each time
for(shift =0; shift <100; shift ++){
// We set a sinusoid in the vector (converting [-1f, 1f] -> [0, 255]) and we shift it
for(i=0; i!=vector.size; i++) vector.uchars[i]=128+127*sinf(i/2.f+ shift);
//If it is not the first time we erase the previous graph by putting back (ANSI escape code) the cursor 16 lines (height of the graph) up. 'sprint' stand for fprint on stderr
if (shift != 0) blc_eprint_cursor_up(16); //blc_text.h function
/*We graph the vector, with title "vector test", the height of 16 chars, the limit max 256 and limit min 0.
Text on abscissa "position" and text on ordinate "intensity"*/
vector.fprint_graph_uchars(stderr, "Vector test", 16, 256, 0, "position", "intensity");
//We stop 100ms to let time to the user to see the graph.
usleep(100000);
}
...
```
Which produces :

These displays could be dynamical as well
