Declare all differents classes corresponding to main jelix selectors
a selector is a string refering to a file or a ressource, by indicating its module and its name. For example : "moduleName~resourceName". There are several type of selector, depending on the resource type. Selector objects get the real path of the corresponding file, the name of the compiler (if the file has to be compile) etc. So here, there is a selector class for each selector type.
