    Merge pull request #69 from Tieske/master
    general updates, mainly added CONTRIBUTING.md
    Merge pull request #1 from mark-otaris/patch-1
    Caught red handed, after a shameless copy :smile:. Thx for the fix
    This is Penlight, not Busted
    added - a shameless copy of busted - CONTRIBUTING.md file

    Merge pull request #67 from Tieske/add_executeex
    added utils.executeex, which also returns output of stdout and stderr
    updated, using readfile now, remove obsolete os.remove commands
    Merge pull request #66 from Tieske/fix_temp
    windows environment variable TMP is deprecated, use TEMP
    mode binary mode optional (binary would require platform specific line \ 
endings to be converted which is not very portable, and mostly just text will \ 
do)
    update: read files in binary mode
    added utils.executeex, which also returns output of stdout and stderr
    windows environment variable TMP is deprecated, use TEMP
    HTML mode skips DOCTYPE; no globals harmed outside pl.utils
    Merge pull request #64 from Tieske/fix_dir
    fixed makepath creation, added/updated some documentation
    fixed dirpath creation, added/updated some documentation
    basic parser handles comments, and HTML mode is working nicely with \ 
real-world HTML
    use LOM ordered attributes when stringifying if present (Danny).
    manual merge of John Schember's readonly table support
    Merge pull request #61 from user-none/isempty
    Thanks, John!
    Merge pull request #62 from CoolisTheName007/patch-2
    Transform using values as keys.
    missing locals
    Set.issempty mispelling; default ctor borked; more tests
    Transform using values as keys.
    Merge remote-tracking branch 'upstream/master' into empty
    Add function to check if an object is empty.
    Merge pull request #53 from pkazmier/master
    Added iterators to allow traversing tables in a sorted manner
    Merge pull request #60 from theypsilon/master
    base class methods invocation possible not only in method constructor _init
    Adding new class method 'base' which can be used for calling base class \ 
methods easily
    pl.class broke with classes that redefined __newindex; OrderedMap can now \ 
use normal indexing to assign keys in order
    Merge pull request #54 from CoolisTheName007/patch-1
    Typo fixed, libarary->library
    Typo fixed.
    Added tablex.sort and tablex.sortv to iterate over sorted elements
    There are times when it would be convenient to iterate over a table
    either by sorted keys or values. There is an example of this in the
    PIL book. I added the two functions to tablex module, added two test
    cases, and updated the PL manual.
    Merge pull request #51 from pkazmier/master
    Thanks!
    lapp.add_type was broken due to uninitialized table variable.
    The variable `types` was not initialized preventing `add_type` from
    appending custom types to the variable. I also added a new test to
    cover this test case in the future.
