lua.wetgenes.plate.table_lookup
value=wetgenes.plate.table_lookup(name,data)
look up name inside data and return the value we found if we don't find anything then we return nil
name.name.name syntax may be used to reference tables within tables.
A name that looks like a number may be converted into a number if it doesnt exist as a string key, so "array.1" can be used to return the first item from an array.
