Support for Query Forms

[lauratinnel]

It would be really helpful to be able to define query forms that can be selected and used to fill in details of Gremlin queries under the covers. For example, the query

g.V().has('name',within('RussianCulture')).bothE('susceptible_to').has('score', gt(5.0)).as('e').bothV().as('v').select('v')

Might have a form that allows the user to specify the culture and score values.

Display higher susceptibility biases.
Culture: [____________]
Susceptibility Score:  [ 5.0 ] (default)
