// DESCRIPTION:
//
// Produces the MEL command "pick".
//
// This simple plug-in demonstrates the pick-by-name functionality.
// Simply execute "pick <object_name>" in the command window.
// Also, some pattern matching is possible. For example, "pick surface*" 
// will pick all objects whose name begins with "surface".
//
// Example:
//
//  doPick curveShape1
//  doPick "curveShape*"
//
