Points Enclosed in a Curve(drawn in rhino)

hi all

i have been trying to make this simple script where i can pick a curve/profile and its corner point and the script gives me the desired brick course. I already have analysed patterns occurring in various brick-courses.

this is how i proceeded:

1. Firstly i made a point grid. PS: I didn't make a rectangular grid but by moving points in series, first vertically and then horizontally as per the required pattern of the brickwork. ( As that gives me more flexibility to space grids as per the brick-course in the initial stage)

Results are like this:

so as one can see from the images above that i have the base grid, just need to make rectangles around it with appropriate dimensions.

Now the real problem, lets take the case of stretcher bond:

As soon as i define a particular curve and a base point, the result is this

I want to find an effective way to select just the points that are enclosed in the geometry(geometry has been drawn in rhino), i am attaching a part of the script, please help..!!
