/**
 * Updatable Styled Query
 * 
 * This example adds a toolbar button which creates an updatable styled query or updates it
 * if it is already created. Each update modifies query's filter and its style.
 * Query legend item can be saved in the workspace (explicitly in the user interface or from
 * code using $GP.user.workspaces)
 * 
 * Try with http://demo.hexagongeospatial.com/communityportal/Examples.aspx?gpw=85da87cf-2a3a-47cf-b69e-7cf5372421e8
 * 
 * Please note that:
 *   - this link may soon expire
 *   - the code below must be pasted manually in the javascript console
