Report function shadowing

[gkaguirre]

Functions in Installed toolboxes may shadow either Matlab toolboxes, or one installed toolbox may shadow components of other installed toolboxes.

A useful enhancement for TbTb would be to have it report when a function in an installed toolbox has shadowed either the matlab version or the version in another toolbox. A flag could be set to over-ride this reporting if the user wished.

This function (UniqueFuncNames) on matlab central reports all shadowed functions:
https://www.mathworks.com/matlabcentral/fileexchange/27861-uniquefuncnames

The report that this function produces includes many, many examples of functions in matlab toolboxes shadowing each other. Perhaps this UniqueFuncNames could be modified to exclude these collisions.

A very fancy enhancement would be the ability to specify, within the json file for toolbox, the identities of functions that are intentionally shadowing matlab built-in (or other) functions, and thereby silence reporting of those collisions.
