Edit dev doc to a minimal level

[Remi-C]

The dev doc should be at a minimum level before releasing to first version milestone@"Release 1.0" This include

• a little bit of high level dev doc (principle of each feature implementation, pointer to most important functions)
• a little bit of issue specific doc, that is explain what was tried but unsuccessful.

[Remi-C]

Here is the list of pre-filled doc

• https://github.com/Remi-C/interactive_map_tracking/wiki/%5Bdev%5D-RoadMap
  Simply details the step (about 4-5) for grouping of camera tracking event
• https://github.com/Remi-C/interactive_map_tracking/wiki/%5Bdev%5D-Detailled-doc
  I already detailed as far as I knew the plugin mechanism.
  • It need to be completed with some real function name (2-3, only most important), and real event name (same, only most important)
  • The saving behaviour is not complete (I don't know more)

When citing actual function name, you can use the sign before and after, it will create an inline codelike this` You can also add 4 spaces to create a code block if you want to cite several line

this is a code block
Yeah
my function blabla

@yoyonel : this need to be done to close the milestone !

[Remi-C]

@yoyonel you can use the command [[/images/plugin/dev_plugin_principle_schema.png]] to include the image in the wiki. In the site, you have to use (without extra space) ![](/Remi-C/interactive_map_tracking.wiki//images/plugin/dev_plugin_principle_schema.png)

Update and add documentations for dev sides of our project. Add events/signals with (briefs) descriptions and urls/link to them (in QGIS API documentation, can be useful for futur dev/contributors)
