    Replace old Feature implementation

    * old implementation was "fat", i.e., each Feature had to have its own
      class on the Scala side of things
    * knowledge about validity is on Tcl side; led to double effort to check
      for invalid values, which went out-of-sync
    * removed fat layer, replaced by thin, generic implementation:
      Features have a name and a map of properties, mapping strings to
      strings; all properties are passed exactly as-is to Tcl
    * special case: added "Enabled" -> "true" in all cases, reasoning: if
      somebody goes to all the trouble of defining a Feature, it should
      usually be enabled
    * can be overridden explicitly (for whatever reason)

    Update usage info and man pages

    * man page is generated by Usage; not as nicely formatted, but readable
    * simplifies maintenance by keeping information in one place only

    Improve error messages from parser

    * mostly fine-tuning to make sure the lastParser value gives the user
      the right idea about the mistake
    * see also the script parserTest.sh in Seafile/TAPASCO to generate a lot
      of error messages automatically

    Dump example jobs, if none are specified

    * Configuration dumping should automatically use JobExamples to generate
      a list with on instance of each job
    * useful for users to get a starting point for their configs
    * updated README.md accordingly

    Finish work on new parser and property tests

    * all parsers implemented, spec'ed and debugged
    * wrote a lot of property tests, caught some bugs I'd never have found
      otherwise, very nice
    * changed a few bits and pieces, need to rewrite man and usage

    Bugfix exceptions in MemInfo when /proc/meminfo is unavailable

    * not portable, sometimes /proc/meminfo may not exist (e.g., Darwin)
    * will warn once, then deactivate all resource checks on mem

    Continue work on new parser

    * split classes into more sub objects
    * each subobject needs its own test suite with at least one test for
      each parser defined therein
    * got better with scalacheck, tests are stronger

    Implement new parser with better error handling

    * error messages of the current command line argument parsrer are
      abysmal, extremely confusing to users
    * since scala parser combinators do not feature cuts, it is very
      difficult to provide better error messages
    * started re-implementation of parser using 'fastparse'
    * works extremely well so far
