Example usage

const { Host } = require("@e-mc/core");

Host.loadSettings({ // Global
    process: {
        thread: { limit: 8 }
    },
    permission: {
        disk_read: ["**/*"],
        disk_write: ["/tmp/**"]
    }
});

NOTE: @e-mc/core is mostly a collection of abstract base classes which cannot be instantiated. Host is more commonly called through @e-mc/file-manager.
