I'm submitting a
[x] question about the decisions made in the repository
Issue description
I wonder if I can change the default theme to Light, not Cosmic, I tried everything in ThemeSwitcherComponent, but it seems to get "cosmic" theme always in this.themeService.getJsTheme() method, how can I override the theme or workaround it
Its very easy, man. :)

Thank you for the answer !
It would be great if this was documented somewhere, maybe here: https://akveo.github.io/nebular/#/docs/guides/enabling-theme-system
And how to change the template to a corporate template?
Line 95 change name: 'corporate' for corporate look and feel
