Launch a vrep pool before starting algorithm

[Grenadingue]

• Add vrep executable full path to the config file
• In frontend, use a parameter field to specify a number of vrep instances to launch
• Send the value of the previously created field to web server
• In web server, launch the N vrep instances before starting the c++ algorithm
  • Launch a vrep instance on a generated port
  • Also specify in parameters the 2w1a.ttt scene
  • Add the generated port to a list
  • Catch vrep process close event
  • If process failed, remove the port from the list, an try to launch another instance with another port
  • When all vrep process have spawned
  • Concatenate the list of all the ports in a string like 4000,4001,4002
  • Put the created string in the algorithm parameters as vrepPool
  • Then the algorithm can be launched

Note: The scene path must be the full path

Current advancement :

• [x] Node.js take v-rep path as parameter
• [x] Node.js launch X instances of V-Rep using different port
• [x] Those port are sent to the cpp server
• [x] Frontside allow the user to set the number of v-rep instances and send it to the Node.js
• [x] Catching V-Rep error
• [x] Manually strop V-Rep instances
