nav_link_to.rb

  # Generate a navigation link. The link will include the "nav-link" CSS class
  # and if the link's route matches exactly or fuzzy to the current path add
  # the "active" CSS class.
  #
  # Usage:
  #
  # A navigation link using a generic route helper.
  #
  #   <%= nav_link_to("manage.sidebar.dashboard", manage_path) do %>
  #     <i class="fas fa-home"></i>
  #   <% end %>
  #
  # A navigation link using a fuzzy match.
  #
  #   <%= nav_link_to("manage.sidebar.training", manage_member_training_path, fuzzy_match: ["/members/training", "/member_training"]) do %>
  #     <i class="fas fa-training"></i>
  #   <% end %>
