create Places table

[ClimbsRocks]

this is just the unique list of places from our raw_data_import table.

we should have a count of each place too, so we're only making requests to Unlock Places for places with more than 5 users.

steps:

1. write query to group by place
2. create a Places table
3. figure out how to save data from the query into the Places table
4. figure out how to add a count to the Places table.

did it! and documented in the mysql wiki.
