Bootstrap4 Nav

{*
*   Template name: Bootstrap4 Nav
*   -------------------------------------
*
*   This is the default template for use with the "Navigator" module. It is capable of generating
*   the three stock Bootstrap Navbar types: default, static and fixed. It can also be customised
*   with the included Bootstrap4 classes for light and dark.

*   Customisations should be made in the "Bootstrap4 Settings" template and NOT in this file, and
*   the following can be done there:
*
*    - Change navbar position
*    - Change navbar brand text
*    - Change navbar brand logo
*    - Change toggler alignment
*    - Switch dark/light Bootstrap theme
*
*   Note: this template should be set as the "default" template of its type for the Bootstrap4 theme
*
