Standard Indicator Release

Good Morning.

I am wondering whether we could get source of the standard packaged indicators?

I can see that they Ichimoku indicator release would not be possible since it contains a filled area, but the others would be really helpful since that way we can modify from existing standard instead of having to create our own analogues.

It is easy to create new stuff, and it isn't that all important, but it would serve as nice examples for starters, and decrease time for some developers.

For example, the Linear Regression RSquared indi, rather than making a wrapper and then drawing the conformity line it'd be nice just to add it to an existing source and build it under a different name.
