Require

Loads the given module. The function starts by indexing the loaded table to determine whether modname is already loaded. If it is, then require returns the value stored at loaded[modname]. - Module names are the path to a file relative to the resource. - The module name must point to a .lua file. - Use . to separate directories in a path. - Modules can be loaded from external resources using @resource.modname.

Examples

require '@resource.client.modname'

Client modules must be defined in the `file` section of the resource manifest.
```lua
    file 'modname.lua'
    -- or
    files {
    'modname.lua'
    }
```
