49 allow access to loadparm variables from inside ejs scripts in web apps
51 can be called in 4 ways:
53 v = lp.get("type:parm"); gets a parametric variable
54 v = lp.get("share", "type:parm"); gets a parametric variable on a share
55 v = lp.get("parm"); gets a global variable
56 v = lp.get("share", "parm"); gets a share variable
58 the returned variable is a ejs object. It is an array object for lists.
