Remove parameter
 - remove connection : done
 - remove from ui
 - remove declaration from shader text
 - let the user remove it from the code, do a search and replace function later

load parameter
    - problem loading param name and value
DoUNITTEST
compile the project
parameter range value problem

add input datas info (resolution, time etc)

info about the input parameters
import texture
set button to load texture
link texture input to opengl data
