Control the direction of flowcharts in Mermaid

[JamesMcIntyre100]

Problem

• I'm always frustrated when I try to create a flow chart which fits on a peice of paper because I can't control the direction of the arrows.
• I would like it if you could choose which direction the arrows and the next node appeared when I add a new node because I need my flow charts to fit within printable documents which have edges and keys etc which have to be avoided and fit around.

Proposed Solution

• Add an option so that when you add a new node and an arrow with a different direction, this new direction arrow will be used will be used

The newly introduced Block diagrams will allow you to place the nodes in a more granular fashion.

Refer to this answer for an example.

Due to how the layout algorithms work, we cannot specify direction per arrow in normal flowchart. We are making some changes to allow more algorithms, but something like this is out of scope.
