NDN-CCL

NDN regex is used for the trust schema in the config policy manager. The current implementation follows the original from ndn-cxx which expands the NDN regex into a single normal regex expression. This has problems with generality and Boost regex can crash on complex expressions. Now, ndn-cxx has a custom library which directly handles the NDN regex expression at the name component level so that the standard regex library only needs to handle the regex within a single name component.

We should port this to the Common Client Libraries.
