Builds a relative path from the given arguments. Iterates over the arguments and appends
them to the path if defined and non-empty. The arguments are expected to be strings or
integers, but this is not checked.

Examples:
buildPath() --> ""
buildPath("base", "relative") --> "base/relative"
buildPath("base", "") --> "base"
buildPath("", "relative") --> "relative"
buildPath("base", undefined, "relative") --> "base/relative"
buildPath("base", 42, "relative") --> "base/42/relative"
buildPath("base", 0, "relative") --> "base/0/relative"
buildPath("base", "('predicate')") --> "base('predicate')"

@returns {string} a composite path built from all arguments
Builds a relative path from the given arguments . Iterates over the arguments and appends them to the path if defined and non - empty . The arguments are expected to be strings or integers but this is not checked .
