Acyclic graph take

[santiagoginero]

Changes

• Created the function AcyclicGraphTake which accepts a directed, acyclic graph and a list of two vertices, returning the intersection of the in-component of the first vertex (i.e. start vertex) with the out-component of the second vertex (i.e. end vertex).
• Function definition, tests, and documentation are all provided.

Error checking

• The function checks for invalid inputs of the form of the graph not being directed and acyclic, the vertices not being part of the graph, incorrect argument count, among others.

Great job! The code looks good to me. I just have a few comments about the documentation.

**`AcyclicGraphTake`** gives the intersectiom of the out-component of the first vertex
with the in-component of the second vertex;

The last character should be a ":", i.e., what follows is the example for this statement.

The image cuts off the label "1" at the top. Might be another weed in the rasterizer, but you can use this image for now (the width is 478.2):

The same here, the width is 232.2, the image is:

I wonder if smaller sizes you are getting have something to do with scaling.

Thanks! Just finished the changes.
