Point Filtering

[gautegf]

User story #11
Add filtering for points that are:

• "accepted"/not.
• TVU
• THU
• source ID

Should be able to handle switching between different filters without a massive rerender.

Current suggestion:

• slider for <= TVU and THU with an AND/OR option
• radio group for accepted/not accepted/all
• slider for source ID (a bit unsure about this one)

Todo next time for Elevation control and accepted filtering:

• clean the code
• write tests
