Changeset 298

new version of the pulsar archive, uses smarty to separate implementation from interface, a lot of functionality is broken into separate modules Classes/General? is generic classes eg File,Date. Classes/Astro? contains astronomer classes eg MJD,SkyCoord?. Classes/Pulsar? are pulsar specific, most algorithms for dealing with PSRFITS files. SQL queries are encapsulated in classes under Classes/Queries?. The actual pages are under Forms/ and use smarty templates under templates/ to format their output.
