- Allows users to control the node sizing by a particular column present in `.log_df`

 - Important to note that `ofv` cant be used without first calling `add_summary()`, which is consistent with the previous behavior of `color_by` and `include_info`

 - This argument does support logical columns, however I noticed that the normalized sizing can differ here depending when the first `TRUE` value originates. If it's the first value, all the nodes appear smaller. Anywhere else and the "base size" is larger. This observation is likely true for numeric columns too, though is less apparent when the values are all closer to each other.
    - `collapsibleTree::collapsibleTreeNetwork` is only intended to support numeric columns for sizing, so I opted to map these values to: TRUE=5, FALSE=1, NA=3 for the time being. We may want to revisit NA values for both numeric and logical columns

 - Added examples to docs

 - While the implementation and tests are done, I think we still want to revist the NA handling, which also impacts the "start" node size.

 - While updating the vignette, I noticed that the size_by and color_by arguments occasionally didnt line up for numeric columns. Numeric columns need to be sorted first so the right colors are assigned. This was previously "tested" using the character 'run' column, though was more observable when testing against objective function values (which dont necessarily appear in ascending/descending order)

 - uses leafCount, which makes the nodes containing more child nodes, larger

 - Improve formatting of code in some cases

 - They were always NA previously

 - Adds additional tests when required or specified columns are missing

 - doc adjustments

 - If color_by or size_by is specified, ensure these columns are also part of the tooltip. This avoids the need for specifying new columns (e.g., 'Out of Date') in both the tooltip and color_by

 - doc and text adjustments
 - Revert change from previous commit (comment it out) until a decision has been made.
