The goal of this PR is to implement components for traces page according to the wireframes (#12).

At the moment, this PR includes:

• State persistance, user will keep login after page reload
• Loading traces from the API
• Display of total traces count

To do:

• Filter components
• Pagination components
• Table

@LanesGood I believe you can work on styling what you can for this page while I implement the Photos page. In order to populate the development database, please use code from developmentseed/observe-api#25 for the moment.

@vgeorge I'm running the API locally from the branch in developmentseed/observe-api#25 but the dev db is not populating.

Error message:

(node:64472) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 4)

@vgeorge I've started setting up the layout for the pagination, and for the dropdown + length slider featured in this screen. Would you be able to help me hook up the dropdown and length filter so that I can start styling? This is mainly using components developed by @danielfdsilva that I'm not able to implement yet solo.

/cc @sethvincent if you want to take a look

@LanesGood as discussed, I'm merging this at the commit with basic page structure. I've moved last commits to enhance/trace-page-styles branch. Let's work on specific components in separate PRs to be able to review better.
