Pass options to Faker method
Add a method to return kind name

This allows us to return the name of the kind supplied. This is useful
when doing things like “randomFloat|1,1,1”. This will return
“randomFloat”
Get factory name once, instead of substr twice
Use getKind() method
Use call_user_func_array so we can pass options to faker
Test that multiple options are being passed to faker library
Use `;` to split options now
Update reassume to show multiple options
Merge pull request #156 from thephpleague/faker-options
