Select targets according to user's criteria #54
Description
Splitting #28 is individual issues
select as function of magnitude of the star
I don't think we should implement it as it is, as not all catalogs have magnitude in them (most of them won't I guess), but I fancy the idea of being able to sort according to whatever criteria is in the user's catalog
One could imagine an advanced selection popup, that allows the user to browse through the properties of his objects and sort according to these.
Might become a mess if we have a mix of various obsprogram in a single catalog. Also means we have to load all the extra parameters at catalog load, which might slow down the import process for large catalogs. Opinions, @kuntzer ?
