Managing models

[wmburke]

Once we have reworked the model saving system in #7, this is how we make managing models more intuitive.

Each model in the list of models should have a drop down list next to it that contains the following capabilities:

1. Set as Crawl Model If set as the crawl model, the model is the one that will be used by Sparkler for determining relevance. When this happens, the model name will be all pretty - different color/bg, bold, whatever - but it needs to stand out - and also have a hover tip that says: "Active Crawl Model"
2. Rename The user can give the model a new name, since by default it is names after the first query run to create it. These may be non-intuitive and duplicative.
3. Export The user can export the model and save it on their computer.

In addition, the following changes to the interface will need to take place:

1. The Selected Model is the model that is being trained. It's name is shown above the "Create New Model" link and is in bold and a different color or whatever to make it obvious that it's the current one. A hover tip should be added that says, "You are training this model now."
2. Remove the Export model button from the left hand column
3. Importing a model will cause it to become the selected model (not the crawl model).
4. Selecting a model from the list will make it the selected model.
5. It should be possible to select the Crawl Model, eg a model can be the crawl model and be actively trained at the same time (this is current functionality).

The left hand side column should contain these things, in this order:
Search box
Selected Model Name
"Create a New Model"
Import a Model
