include customer classes

I suggest improve the include fetures of calgo.

preset if i'd like to define some customer classes which could be used by other cbot or indicators, i have to define it as an indicator.like this:

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TrendLine
    {
        //......code
     }

without "[indicator....." ,error throws out.and nowhere to place it except indicators.

it's not a good stucture.

i hope there is a inclue place stand with cbots and indicators.
