The options block sets special parameters for the flow graph. \
Only one option block is allowed per flow graph.
Title, author, and description parameters are for identification purposes.
The window size controls the dimensions of the flow graph editor. \
The window size (width, height) must be between (300, 300) and (4096, 4096).
The generate options controls the type of code generated. \
Non-graphical flow graphs should avoid using graphical sinks or graphical variable controls.
The id of this block determines the name of the generated file and the name of the class. \
For example, an id of my_block will generate the file my_block.py and class my_block(gr....
The category parameter determines the placement of the block in the block selection window. \
The category only applies when creating hier blocks. \
To put hier blocks into the root category, enter / for the category.
