This service introduces callstack similarity for merge recommendations.
/candidates
endpoint provides a list of groups that are similar to a given fingerprint. Similarity is calculated by the edit distance of the callstacks. A diff of the callstacks is provided for each candidate fingerprint.

}]
}
/summary
endpoint provides information for each fingerprint in a given project. It includes the number of candidate fingerprints and their edit-distance.

- Both endpoints have tunable parameters:
"threshold": 5, // minimum callstack length to be considered "truncate": 50, // shorten the callstack before comparing "intersection": 3, // callstacks need to have at least n frames in common "distance": 10, // minimum distance to be considered a candidate
