/**
 * Creates {@code TextResource}s backed by sources such as strings, files, and archive entries.
 *
 * Example usages:
 *
 * 
 * def sourcedFromString = resources.text.fromString("some text content")
 *
 * def sourcedFromFile = resources.text.fromFile("path/to/file.txt")
 *
 * task someTask {} // assumption: produces a text file and declares it as output
 * def sourcedFromTask = resources.text.fromFile(someTask)
 *
 * def sourcedFromArchiveEntry =
 *   resources.text.fromArchiveEntry("path/to/archive.zip", "path/to/archive/entry.txt")
 *
 * configurations { someConfig } // assumption: contains a single archive
 * def sourcedFromConfiguration =
 *   resources.text.fromArchiveEntry(configurations.someConfig, "path/to/archive/entry.txt")
 *
 * def sourceFromUri = resources.text.fromUri("https://path/to/the/resource")
 * 
 *
 * File based factory methods optionally accept a character encoding. If no encoding is specified,
 * the platform's default encoding is used.
