Develop interface to search GRIST for grant information

See parent ticket #6 (closed)

Develop an interface to search GRIST for grant information using Yuci's API. This can use the normal GRIST API (https://europepmc.org/GristAPI) until #26 (closed) is implemented.

Example:http://www.ebi.ac.uk/europepmc/GristAPI/rest/get/query=gid:081052&resultType=core&format=json

Users should be able to search by Grant ID or PI last name

Search return a grant data object, and display a list of grant IDs and their associated pi names (in parenthesis), with checkboxes. When the user checks a grant, this should be added to a visible list from which grants can also be removed, and to the manuscript version fragment in the following format:

metadata.fundingGroup = [
  {
    fundingSource: Grant.Funder.Name
    awardId: Grant.Id
  }
]

Data from the Grant object will be used in other parts of the form (#28 (closed), #29 (closed))
