Create search engine amongst employees

[mariellelilja]

• Search bar
• Search page
• Hits page

To be able to perform search based on Employee's attributes such as (see all on #45 ) :

• Name
• Skillset tags
• Location, etc

Additionally (might be for another iteration/ another issue):

• Enable combined searches
• Enable filtering among hits
• Enable filtering in full Employee DB, without specific search
