Create abstract component for a gallery display

[MaHaWo]

Against original ideas it is not practical to unify this with the table display feature, hence a separate component based on flowbite-gallery is necessary.

• needs to be pageinated
• needs to have subcomponents for the elements to be displayed
  • these need to display individual children: Avatar, name...
  • they need to have a link (will lead to children's milestone/survey overview and information in the final product)
  • needs to eat an array of objects that represent children which is ordered alphabetically by children name
  • upper left element needs to be a dummy that leads to the registration page for a new child.
