Simple Cone Search

This specification defines a simple query protocol, named Simple Cone Search, for retrieving records from a catalog of astronomical sources. The query describes a sky position and an angular distance, defining a cone on the sky. The response returns a list of astronomical sources from the catalog whose positions lie within the cone, formatted as a VOTable.

The current version aims essentially at aligning this specification with the Data Access Layer (DAL) landscape at the time of writing.

It also currently includes addition of a feature to allow for filtering in a specific time window.

Keep in mind to use the --recurse-submodules option when cloning the repository.
