Added qtip library for popup displays - integrated with ChemSpec output.
Chemical Editor tab results are now filled with a single click. Note: this
fix involved making a synchronous, "sjax" call. Also added standardizer to
the jchem_rest services, which is called before grabbing results to fill
the results table. This also fixes the child-parent issue in the GenTrans
output.
Added "back" button option for "landing" page.
Wrapped tautomer and stereoisomer outputs in table with popup tables on
mouseover. Used qtip for popups.
Deleted some unnecessary files and made some minor changes to others.
